The Lightweight Construction Alliance BW is the central point of contact for all players in the field of lightweight construction in the State and acts in their interests at national and international level. Professor Markus Milwich from the German Institutes of Textile and Fiber Research Denkendorf (DITF) represents the agency.

The use of lightweight materials in combination with new production technologies will significantly reduce energy consumption in transportation, the manufacturing industry and the construction sector. Resources can be saved through the use of new materials. As a cross-functional technology, lightweight construction covers entire value chain from production and use to recycling and reuse.

The aim of the state government is to establish Baden-Württemberg as a leading provider of innovative lightweight construction technologies in order to strengthen the local economy and secure high-quality jobs.

Among others, the "Lightweight Construction Alliance Baden-Württemberg" will continue the nationally renowned "Lightweight Construction Day", which acts as an important source of inspiration for a wide range of lightweight construction topics among business and scientific community.

Professor Milwich, an expert with many years of experience and an excellent network beyond the State's borders, has been recruited for this task. In his role, Milwich also represents the state of Baden-Württemberg on the Strategy Advisory Board of the Lightweight Construction Initiative of the Federal Ministry for Economic Affairs and Climate Action, which supports the cross functional-technology and efficient transfer of knowledge between the various nationwide players in lightweight construction and serves as a central point of contact for entrepreneurs nationwide for all relevant questions.

From 2005 to 2020, Professor Milwich headed the Composite Technology research at the DITF, which was integrated into the Competence Center Polymers and Fiber Composites in 2020. He is also an honorary professor at Reutlingen University, where he teaches hybrid materials and composites. "Lightweight design is an essential aspect for sustainability, environmental and resource conservation. I always showcase this in research and teaching and now also as a representative of the lightweight construction community in Baden-Württemberg," emphasizes Professor Milwich.

DITF: Biopolymers from bacteria protect technical textiles

Textiles for technical applications often derive their special function via the application of coatings. This way, textiles become, for example wind and water proof or more resistant to abrasion. Usually, petroleum-based substances such as polyacrylates or polyurethanes are used. However, these consume exhaustible resources and the materials can end up in the environment if handled improperly. Therefore, the German Institutes of Textile and Fiber Research Denkendorf (DITF) are researching materials from renewable sources that are recyclable and do not pollute the environment after use. Polymers that can be produced from bacteria are here of particular interest.

However, these consume exhaustible resources and the materials can end up in the environment if handled improperly. Therefore, the German Institutes of Textile and Fiber Research Denkendorf (DITF) are researching materials from renewable sources that are recyclable and do not pollute the environment after use. Polymers that can be produced from bacteria are here of particular interest.

These biopolymers have the advantage that they can be produced in anything from small laboratory reactors to large production plants. The most promising biopolymers include polysaccharides, polyamides from amino acids and polyesters such as polylactic acid or polyhydroxyalkanoates (PHAs), all of which are derived from renewable raw materials. PHAs is an umbrella term for a group of biotechnologically produced polyesters. The main difference between these polyesters is the number of carbon atoms in the repeat unit. To date, they have mainly been investigated for medical applications. As PHAs products are increasingly available on the market, coatings made from PHAs may also be increasingly used in technical applications in the future.

The bacteria from which the PHAs are obtained grow with the help of carbohydrates, fats and an increased CO2 concentration and light with suitable wavelength.

The properties of PHA can be adapted by varying the structure of the repeat unit. This makes polyhydroxyalkanoates a particularly interesting class of compounds for technical textile coatings, which has hardly been investigated to date. Due to their water-repellent properties, which stem from their molecular structure, and their stable structure, polyhydroxyalkanoates have great potential for the production of water-repellent, mechanically resilient textiles, such as those in demand in the automotive sector and for outdoor clothing.

The DITF have already carried out successful research work in this area. Coatings on cotton yarns and fabrics made of cotton, polyamide and polyester showed smooth and quite good adhesion. The PHA types for the coating were both procured on the open market and produced by the research partner Fraunhofer IGB. It was shown that the molten polymer can be applied to cotton yarns by extrusion through a coating nozzle. The molten polymer was successfully coated onto fabric using a doctor blade. The length of the molecular side chain of the PHA plays an important role in the properties of the coated textile. Although PHAs with medium-length side chains are better suited to achieving low stiffness and a good textile handle, their wash resistance is low. PHAs with short side chains are suitable for achieving high wash and abrasion resistance, but the textile handle is somewhat stiffer.

The team is currently investigating how the properties of PHAs can be changed in order to achieve the desired resistance and textile properties in equal measure. There are also plans to formulate aqueous formulations for yarn and textile finishing. This will allow much thinner coatings to be applied to textiles than is possible with molten PHAs.

Other DITF research teams are investigating whether PHAs are also suitable for the production of fibers and nonwovens.

DITF: Lignin coating for Geotextiles

Textiles are a given in civil engineering: they stabilize water protection dams, prevent runoff containing pollutants from landfills, facilitate the revegetation of slopes at risk of erosion, and even make asphalt layers of roads thinner. Until now, textiles made of highly resistant synthetic fibers have been used for this purpose, which have a very long lifetime. For some applications, however, it would not only be sufficient but even desirable for the auxiliary textile to degrade in the soil when it has done its job. Environmentally friendly natural fibers, on the other hand, often decompose too quickly. The German Institutes of Textile and Fiber Research Denkendorf (DITF) are developing a bio-based protective coating that extends their service life.

Until now, textiles made of highly resistant synthetic fibers have been used for this purpose, which have a very long lifetime. For some applications, however, it would not only be sufficient but even desirable for the auxiliary textile to degrade in the soil when it has done its job. Environmentally friendly natural fibers, on the other hand, often decompose too quickly. The German Institutes of Textile and Fiber Research Denkendorf (DITF) are developing a bio-based protective coating that extends their service life.

Depending on humidity and temperature, natural fiber materials can degrade in the soil in a matter of months or even a few days. In order to significantly extend the degradation time and make them suitable for geotextiles, the Denkendorf team researches a protective coating. This coating, based on lignin, is itself biodegradable and does not generate microplastics in the soil. Lignin is indeed biodegradable, but this degradation takes a very long time in nature.

Together with cellulose, Lignin forms the building materials for wood and is the "glue" in wood that holds this composite material together. In paper production, usually only the cellulose is used, so lignin is produced in large quantities as a waste material. So-called kraft lignin remains as a fusible material. Textile production can deal well with thermoplastic materials. All in all, this is a good prerequisite for taking a closer look at lignin as a protective coating for geotextiles.

Lignin is brittle by nature. Therefore, it is necessary to blend the kraft lignin with softer biomaterials. These new biopolymer compounds of brittle kraft lignin and softer biopolymers were applied to yarns and textile surfaces in the research project via adapted coating systems. For this purpose, for example, cotton yarns were coated with lignin at different application rates and evaluated. Biodegradation testing was carried out using soil burial tests both in a climatic chamber with temperature and humidity defined precisely according to the standard and outdoors under real environmental conditions. With positive results: the service life of textiles made of natural fibers can be extended by many factors with a lignin coating: The thicker the protective coating, the longer the protection lasts. In the outdoor tests, the lignin coating was still completely intact even after about 160 days of burial.

Textile materials coated with lignin enable sustainable applications. For example, they have an adjustable and sufficiently long service life for certain geotextile applications. In addition, they are still biodegradable and can replace previously used synthetic materials in some applications, such as revegetation of trench and stream banks.

Thus, lignin-coated textiles have the potential to significantly reduce the carbon footprint: They reduce dependence on petroleum-based products and avoid the formation of microplastics in the soil.

Further research is needed to establish lignin, which was previously a waste material, as a new valuable material in industrial manufacturing processes in the textile industry.

The research work was supported by the Baden-Württemberg Ministry of Food, Rural Areas and Consumer Protection as part of the Baden-Württemberg State Strategy for a Sustainable Bioeconomy.

European-produced nanotubes and nanotube derivatives will be primarily supplied to our customers in central and western Europe, North America, and Asia,” said OCSiAl Group Senior Vice President Gregory Gurevich.
 
In addition to synthesizing nanotubes, the facility will manufacture nanotube suspensions for lithium-ion battery manufacturers in Europe, the US, and Asia – enough to enhance the performance of more than 1 mln electric cars with an average battery capacity of 75 kWh per car. OCSiAl nanotubes create long and robust electrical networks between active material particles, improving key battery characteristics, including cycle life, lower DCR, C-rate performance, and cohesion between active battery material particles, making the battery electrodes more durable. Graphene nanotubes unlock new battery technologies, including high-silicon content anodes, thick LFP cathodes, fast-charging graphite anodes, and more. They can be applied in both conventional and emerging battery tech, such as a dry battery electrode coating process, and solid-state batteries.
 
As well as synthesizing nanotubes and producing suspensions, OCSiAl project includes manufacturing of nanotube concentrates for high-performance polymers. The project has passed environmental impact assessment and it is 100% powered by green energy. It enjoys support from Serbian municipal and national governments. The plant is planned to be certified in accordance with ISO 9001, ISO 14001, and ISO 45001, and to be compliant with the IATF 16949 automotive industry standard. The project will create more than 200 job opportunities for engineers, scientists, managers, operators, and administrative staff.
 
Currently, OCSiAl has an extensive manufacturing system of nanotube-based products in the regions of highest market demand, such as China, Japan, Sri Lanka, Brazil, Malaysia, and other countries. The Serbia nanotube hub will operate in conjunction with the company’s operational R&D center and planned graphene nanotube synthesis facility in Luxembourg.

Nanomodified polymerstent: Novel technology for tumour therapy

  • Electromagnetically heatable nanomodified stent for the treatment of hollow organ tumours wins second place at the RWTH Innovation Award

Almost every fourth person who dies of cancer has a hollow organ tumour, for example in the bile duct or in the oesophagus. Such a tumour cannot usually be removed surgically. It is only possible to open the hollow organ for a short time using a stent, i.e. a tubeshaped prosthesis. However, the tumour grows back and penetrates the hollow organ through the stent. Ioana Slabu from the Institute of Applied Medical Technology and Benedict Bauer from the Institut für Textiltechnik of RWTH Aachen University have now developed a novel technology for the therapy of hollow organ tumours, which was awarded second place in the RWTH Innovation Award. This involves a polymerstent that contains magnetic nanoparticles. When electromagnetic fields are applied, these nanoparticles lead to a controlled heating of the stent material and thus of the tumour. Because the tumour reacts much more sensitively to heat than healthy tissue, it is destroyed and the hollow organ remains open. Thus, the stent develops a self-cleaning effect.

Ioana Slabu of the AME explains: "Not only can we drastically reduce treatment costs, but above all we can provide relief for millions of patients worldwide.
 
A manufacturing process and proof of concept for magnetic hyperthermia are already in place. This novel technology has a very high development potential because it can also be used for tumours in other parts of the body such as the prostate, stomach, intestine or urinary bladder or for cardiovascular diseases.  

The AiF/IGF project started under the project title "ProNano" funded by BMWK. Now the approval for the follow-up project "ProNano2" has also been received. The approved project is called: "Validation of the innovation potential of heatable stents for heat-induced treatment of cavity tumours" and is funded by BMBF in course of the VIP+ program. With the Clinic for General, Visceral and Transplantation Surgery of the University Hospital Aachen and the Institute for Technology and Innovation Management at RWTH Aachen University, the consortium is enriched by clinical and economic expertise. Every year, RWTH Aachen University honours particularly innovative university projects with the Innovation Award. Professor Malte Brettel, Prorector for Business and Industry, presented the certificates to four outstanding projects as part of RWTHtransparent.

Fraunhofer CPM develop programmable material for ergonomic lying position

Many people across the world are bedridden – be it due to illness, an accident or old age. Because those affected often cannot move or turn over by themselves, they often end up with very painful bedsores. In the future, it should be possible to avoid bedsores with the help of materials that can be programmed to entirely adapt their form and mechanical properties. For example, the body support of mattresses made from programmable materials can be adjusted in any given area at the push of a button. Furthermore, the support layer is formed in such a way that strong pressure on one point can be distributed across a wider area. Areas of the bed where pressure is placed are automatically made softer and more elastic. Caregivers can also adjust the ergonomic lying position to best fit their patient.

Areas of the bed where pressure is placed are automatically made softer and more elastic. Caregivers can also adjust the ergonomic lying position to best fit their patient.

Materials and microstructuring
Materials for applications requiring specific changes to stiffness or shape are being developed by researchers from Fraunhofer CPM, which is formed of six core institutes with the aim of designing and producing programmable materials. So, how can we program materials? “Essentially, there are two key areas where adjustments can be made: the base material – thermoplastic polymers in the case of mattresses and metallic alloys for other applications, including shape memory alloys – and, more specifically, the microstructure,” explains Dr. Heiko Andrä, spokesperson on the topic at the Fraunhofer Institute for Industrial Mathematics ITWM, one of the Fraunhofer CPM core institutes. “The microstructure of these metamaterials is made up of unit cells that consist of structural elements such as small beams and thin shells.” While the size of each unit cell and its structural elements in conventional cellular materials, like foams, vary randomly, the cells in the programmable materials are also variable – but can be precisely defined, i.e., programmed. This programming can be made, for example, in such a way that pressure on a particular position will result in specific changes at other regions of the mattress, i.e., increase the size of the contact surface and provide optimal support to certain areas of the body.

Materials can also react to temperature or humidity
The change in shape that the material should exhibit and the stimuli to which it reacts - mechanical stress, heat, moisture or even an electric or magnetic field - can be determined by the choice of material and its microstructure.

The journey to application
A single piece of material can take the place of entire systems of sensors, regulators and actuators. The goal of Fraunhofer CPM is to reduce the complexity of systems by integrating their functionalities into the material and reducing material diversity. We always have industrial products in mind when developing the programmable materials. As such, we take mass production processes and material fatigue into account, among other things,” says Franziska Wenz, deputy spokesperson on the topic at the Fraunhofer Institute for Mechanics of Materials IWM, another core institute of Fraunhofer CPM. The initial pilot projects with industry partners are also already underway. The research team expects that initially, programmable materials will act as replacements for components in existing systems or be used in special applications such as medical mattresses, comfortable chairs, variable damping shoe soles and protective clothing. “Gradually, the proportion of programmable materials used will increase,” says Andrä. Ultimately, they can be used everywhere – from medicine and sporting goods to soft robotics and even space research.

Swiss Textile Machinery technology and innovations for technical textiles

New ideas were exchanged, brainstormed, and discussed freely at members’ booths at the Swiss Textile Machinery Pavilion during the recent Techtextil in Frankfurt. “Customers and researchers met Swiss textile machinery companies to explore the possibility of the not-yet-invented. “We regard our Pavilion as the place where future innovations catch a spark,” says Cornelia Buchwalder, Secretary General of the Swiss Textile Machinery Association. Further developments in the field of hybrid yarns were a hot topic. One example of this involves producing a yarn which has all the typical characteristics and advantages of carbon – but which also prioritizes careful use of resources, combining carbon fibres with thermoplastics.

Technical textiles cover a vast range of applications, and it’s still growing thanks to intensive research by specialist institutes and universities. Many members of the Swiss Textile Machinery Association maintain long-standing partnership with such bodies. Innovations are often joint efforts.

Technical textiles cover a vast range of applications, and it’s still growing thanks to intensive research by specialist institutes and universities. Many members of the Swiss Textile Machinery Association maintain long-standing partnership with such bodies. Innovations are often joint efforts.

Feel-good technical fabrics
Some technical textiles feel like a second skin. A well-known example is activewear from the ‘sport tech’ field. Activewear includes breathable clothing, usually consisting of a three-layer-laminate: an inner lining, a breathable membrane in the center, and an outer fabric. The challenge is to bond the individual layers without losing breathability or softness, while meeting technical requirements such as resistance to a number of wash cycles.

Bonding solutions meeting top quality requirements, as well as ambitious standards for environmental protection and sustainability, were reinvented by the Cavitec brand from the Santex Rimar Group. This company’s hotmelt technology uses one-component polymers applied to textiles in a hot, molten state. Bonding based on hotmelts is both water- and solvent-free. Drying and exhaust air cleaning are not necessary, which is an ecological advantage. Energy consumption is also significantly lower. Cavitec hotmelt technology is also developed for laminated medical protection fabrics which are safe, high-quality and sustainable. These fabrics can be washed, sterilized, and used again.   

A second skin with added value is the result of Jakob Müller Group’s cooperation with an institute for an established outdoor fashion brand. They have devised a heating mat applied as an inner jacket. Outdoor gear with a heated inlay offers the wearer a comfortable feeling even in a cold climate. The heating mat is particularly light, breathable, flexible and adjustable to three temperature levels.

Fabrics with these advantages are now possible thanks to multi direct weaving (MDW) technology from the Jakob Müller Group. A lacquer-insulated heating strand is inserted into the base textile as a ‘meander’ using MDW technology. The technology is offered with both label weaving machines and the latest generation of ribbon weaving machines. The textile pocket calculator is another MDW based future-oriented application developed in cooperation with a textile research institute.

Safety and health
Life-saving reliability is a must for vehicle airbags. They have to fulfil high security aspects, and must remain inflated for several seconds when an accident occurs. Airbags made of flat-woven fabric – cut and seamed – can show weakness at seams during the inflation phase. Latest Jacquard technology by Stäubli enables one-piece-woven (OPW) airbags to be produced, creating shape and structure in a single process. The final product is an airbag consisting of a sealed cushion with woven seams. OPW airbag weaving reduces the number of production steps, and increases the security aspects.
Another big advantage of Stäubli’s new weaving technology is the flexibility in formats required in today’s mid- and upper-range cars, where lateral protection (in the seat or in the roof over the door) has become standard and is designed in line with the car shape. Safe airbags are woven on modern high-speed weaving machines. The warp material, the variety of fabric patterns, and the importance of precisely shaped airbags require the use of a robust and reliable Jacquard machine.

A revolution for orthopaedic patients is a knitting machine from Steiger Participations, which uses compressive yarns developed to meet the needs of the specific health market. This machine model was exclusively designed for production with inlaid elastic yarns and offers optimum performance with guaranteed final product quality.

In the orthopaedic field, many Steiger flat knitting machines have already been operating as automatic, custom-made production systems. For example, the dimensions of an injured limb are taken by the doctor and fed into a web-based application. The doctor selects the compression class in the various sections of the item and a data file created by the software automatically applies a preconfigured program. With no human intervention required, the program is generated and produced on the machine, precisely matching the patient’s dimensions. Each product is different, and generally available within 48 hours.

FET hails INDEX20 impact

Fibre Extrusion Technology, UK is celebrating a successful INDEX20 nonwovens exhibition in Geneva, Switzerland, which closed on 22 October. Although the company has a long history in supplying meltspinning equipment for the nonwovens sector, this represents its first venture at a dedicated nonwovens show.
 
FET’s Managing Director, Richard Slack explains. “Techtextil and ITMA have previously been our main exhibitions of choice, but INDEX20 was an ideal vehicle for FET to launch our new laboratory scale spunbond system, which enables client development of nonwoven fabrics in a number of formats and polymers.”
 
FET already has spunbond systems in the field, including composite systems which utilise both spunbond and meltspun functions. The growth in global nonwovens technology, partly driven by demand for pandemic-related materials, is forecast to continue.

“We were delighted with the response at INDEX”, continued Richard Slack. “There was considerable interest shown in the new spunbond system and its potential for lab scale innovation. It’s clear that the industry is seeking new alternatives to synthetics at the moment, and our technology is able to assist with the testing and assessment of many of the new feedstocks being pioneered in this extremely inventive sector, where everyone is suddenly talking and cooperating with everyone else, regardless of whether they are generally competitors. We recorded in excess of 20 serious enquiries from totally new contacts and sectors, including blue chip companies in the hygiene, medical and packaging industries.”
 
“There were initial concerns about projected attendance figures, especially from China and USA companies, but we experienced good footfall from key decision makers, especially those from Europe. It was encouraging to at last experience the opportunity for face-to-face contact with old and new customers on a large scale and we are now starting to reap the benefits with enquiries continuing to flow in”.

Polynova employs five sales staff and three in logistics, all of whom have a technical background. The company's own warehouse in Rothenburg also ensures the availability of the plastics.

"GRAFE fits perfectly into our product portfolio," says Thomas Weigl, co-owner and responsible for business development at the Swiss distribution company, whose employees recently underwent intensive training in Blankenhain. "Our customers come from the sports goods, housing technology, automotive supplier and medical technology sectors - there are many synergies with GRAFE." Weigl himself has extensive experience in the masterbatch sector and has worked for two companies in the industry - Sukano and Americhem - as managing director. "Swiss companies want Swiss contact persons. We speak the languages German, Italian and French, are on site in the shortest possible time, offer direct contact and understand the needs of the customers and the requirements of the market," he explains. "Polynova is thus faster, closer and more direct." "The Swiss market is large and important for us," reports Theuerkauf and Weigl explains the background: "There are over 300 plastics processors, many are family-run and very technically oriented. The origins of the companies are often in the watch industry and in the production of the smallest precision parts such as gear wheels. In addition, coffee machine manufacturers, medical technology providers and automotive suppliers are important market players. A large number of well-known OEMs are located here."

Even though there are already masterbatch manufacturers in the Alpine country, says the sales expert, no one has the know-how to adjust compounds and masterbatches as perfectly and precisely as the company from Thuringia. In addition to a complete range of colours on practically all plastic substrates, flame retardants, UV additives, thermal stabilisers or lubricants are further examples of the extensive product portfolio. GRAFE is one of the specialists in the modification of thermoplastics and is an innovation driver in the production of colour masterbatches. "The technical possibilities in terms of a state-of-the-art technical centre and production machinery, as well as one of the largest research and development departments in the industry, are also not to be found elsewhere on the Swiss market. Our task now is to bring these to the attention of domestic customers," says Thomas Weigl, co-owner of Polynova AG together with founder Renato R. Huebscher.

BIONIC-FINISH®ECO by RUDOLF GROUP

  • BIONIC-FINISH®ECO Fluorine-Free, Water Repellent Finishes for Ultimate Performance

In recent years, many scientists have shifted from favoring a “primordial soup” in pools of water to hydrothermal vents deep in the ocean as the original source of life on Earth. Regardless what the real beginning really was, water was certainly involved in the process some 3,5bln years ago. And since then, Mother Nature designed many ways to benefit of water and to be sheltered from it. Many engineering challenges humans face can be solved by turning to those 3,5bln years of experience and by using natural design as springboard. That’s biologically inspired engineering or, in short, bionics. BIONIC-FINISH®ECO of RUDOLF GROUP is Mother Nature’s work reproduced on textiles and apparel to protect us from water. To perform.

That’s biologically inspired engineering or, in short, bionics. BIONIC-FINISH®ECO of RUDOLF GROUP is Mother Nature’s work reproduced on textiles and apparel to protect us from water. To perform.

Back in 2003, RUDOLF GROUP borrowed from Mother Nature the idea of dendrimers (from dendron, Greek word for ‘tree’), molecules made of multi-functional branches that interact among themselves, co-crystallize, and self-organize into highly ordered, multicomponent systems. These hyper-branched polymers attach to the textile and embed fluorine-free, durable water-repellent performance.
In 2021 BIONIC-FINISH®ECO comes as a reviewed and extended family of unique nonhalogenated, APEO-free, fluorine-free formulations suited for different materials and designed for different applications and needs. Still very much based on patented dendrimer technology, the new and strengthened BIONIC-FINISH®ECO’s product portfolio:

• Provides non-fluorinated and highly durable water repellent textile finishes for high-performance, professional applications (e.g. when brushing resistance is required);
• Delivers highly efficient and durable performance with low application amounts thus not affecting fabric feel and appearance (e.g. when remarkable softness is important);
• Fulfills a range of challenging technical requirements (e.g. minimal impact on flame retardant properties of technical fibers);
• Is suitable for both sportswear and outdoor applications, as well as for casual apparel and fashion clothing;
• Is bluesign® approved, ZDHC chemical gateway certified and compliant with most RSLs;

BIONIC-FINISH®ECO new portfolio includes universal and versatile solutions targeting the most standard requirements, as well as customized solutions that meet more demanding and specific expectations such as improved resistance to dry-cleaning. “None of us can entirely predict where our voyage will lead” says Dr. Gunther Duschek, RUDOLF GROUP Managing Director. “However, BIONIC-FINISH®ECO of RUDOLF GROUP will always be the fluorine-free, durable water repellent for ultimate  performance. As it is today”.

Arginine coating of non wovens reduce infectivity of SARS-CoV-2

Patients as well as air-condition and ventilator systems spread SARS-CoV-2 virus as aerosols which settle on surfaces and remain there infective for more than 72 hours. That‘s why the pandemic has triggered an intensive search for Personal Protective Equipment PPE whose surfaces have antiviral properties, e.g. are able to bind and inactivate adhering virus.

In this context the chemical stability of the materials being used for PPE, polypropylene PP and/or polyester PET, is a challenge. More precisely, the absence of so-called ‘functional groups‘, like -OH, -COO-, -NH3+ at the material‘s surface. These groups are the fundamental basis for surface chemistry – specifically for attaching antiviral compounds onto the surfaces of man-made fibers.

MaruHachi/AMAC: High-temperature thermoplastic tapes and laminates

With their recently installed high-temperature unidirectional tape line, Japan-based composites manufacturer MaruHachi enables new opportunities for high-end applications in demanding market segments like aerospace, automotive or others outperforming traditional materials based on PP and PA which are already widely available.

In the first phase, MaruHachi will produce up to 40 tons/year and focuses now specifically on high-temperature thermoplastic uni-directional (UD) tapes and multi-layer sheet laminates. The material is based on high-performance fibers like carbon, aramid, glass or natural fibers and the matrix can be high-performance polymers like PPS, PEEK or other higher temperature polymers, which are much tougher than epoxies and easy to recycle. With a width of 500 mm, a specific weight from 60 to 350 g/m2, depending on the chosen material, the lines can operate under temperatures up to 420 degrees Celsius. Working under these extremely high temperatures allows for better material properties of the final application, higher performance, increased resistance and integrated high-performance functionalities e.g. by overmoulding.
