From the Sector

The AVK – Industrievereinigung Verstärkte Kunststoffe – has once again presented its Innovation Awards to companies, institutes and their partners. Three composites innovations were recognised in each of the three categories – “Innovative Products/Applications”, “Innovative Processes” and “Research and Science” – at the new event JEC Forum DACH on 23 November 2021, the first edition of which was held in Frankfurt.

“As usual, the submissions included a lot of very interesting and promising products and processes this year. The Innovation Awards highlight the outstanding efficiency, cost-effectiveness and sustainability of fibre-reinforced plastics as well as the companies and institutes operating in the sector,” explains Dr. Elmar Witten, Managing Director of the AVK. The jury of leading experts from the industry honoured the following innovations this year:

Category “Research and Science”
First place in the “Research and Science” category was awarded to the German Aerospace Center (DLR) for its Bondline Control Technology (BCT). This innovative process is used for quality control and assurance of bonded joints. The core element is a porous fabric which is applied to a joining surface using an epoxy adhesive or matrix resin. Peeling away the fabric creates a chemically reactive and undercut surface and can also be used as a test to check adhesion to the substrate. BCT has potential in a variety of possible applications. For example, peel ply can be replaced by BCT fabric to produce composite components with an optimised joining surface. The cost-effective BCT peel test is suitable for coupon testing and process control. In addition, the combined adhesion test and surface pre-treatment can be used for quality assurance of bonded repairs on fibre composite structures.

Second place was taken by the Institute of Textile Technology (ITA) at RWTH Aachen University and its partners AEROVIDE GmbH, Altropol Kunststoff GmbH, Basamentwerke Böcke GmbH, TechnoCarbon Technologies GbR with “StoneBlade – Lightweight construction with granite for the wind industry”. This innovation enables manufacturers to reduce the amount of non-recyclable materials used in rotor blade construction. At the same time, it reduces the weight of these components and improves the mechanical properties relating to the stability of wind turbines. The innovative approach replaces glass-fibre reinforced plastic in the blade components with hard rock – a natural, cost-effective and recyclable lightweight material. The slabs of rock are cut and ground to a thickness of just a few millimetres and embedded in a fibre composite laminate with carbon fibre, which stabilises them for alternating load cases. The pre-stressed material is pressure-stable in the composite and can absorb tensile forces in the event of continuously alternating loads without any loss of stiffness.

Third place went to the Dresden University of Technology – Institute for Lightweight Construction and Plastics Technology (ILK) with its partner Mercedes Benz AG for the interdisciplinary development of a highly integrated inductive charging module for electric vehicles. The ultra-thin charging module was designed to make optimum use of space in the vehicle underbody without reducing ground clearance. An interdisciplinary approach was adopted for the development process. This involved the electrical, mechanical and process characterisation of high-frequency Litz wires, ferromagnetic foil and metal wire cloth as well as the creation of a simulation model. The result is a demonstrator for a charging system with a structural height of 15 mm and a total weight of 8 kg. It achieves a transmission efficiency of up to 92 percent at 7.2 kW nominal power and active air cooling. The hardware demonstrator was fabricated in a 3-step process using RTM and VARI techniques.

The National Council of Textile Organizations (NCTO), representing the full spectrum of U.S. textiles from fiber through finished products, issued a statement welcoming House passage of a bipartisan infrastructure bill that will provide billions of dollars in new spending to revitalize the nation’s roads, bridges and railways and help reconstitute a domestic supply chain for face masks, isolation gowns and other personal protective equipment (PPE).

“We commend the House for getting the bipartisan infrastructure bill across the finish line today, and we are pleased the legislation will now go to President Biden for his signature. This is the first step in a long-term strategy that is critically needed to permanently onshore PPE production to ensure our nation is prepared for the next health security crisis,” said NCTO President and CEO Kim Glas. “This infrastructure package will help incentivize the reshoring of PPE production by guaranteeing long-term federal contracts and expanding Berry Amendment rules to more federal agencies’ purchases of PPE products, important priorities of the U.S. textile industry.”

NCTO worked with congressional allies to include a version of the Make PPE in America Act, legislation co-sponsored by Senator Rob Portman (R-OH) and Senator Gary Peters (D-MI), in the infrastructure legislative package. The bill ensures all PPE purchased by the Departments of Homeland Security, Health and Human Services and Veterans Affairs are Berry Amendment-compliant (containing 100 percent domestic content); guarantees long-term contracts (a minimum of two years) to U.S. manufacturers; and creates a tiered preference for PPE made in the Western Hemisphere by our free trade partners using U.S. components, after domestic manufacturing capacity has been maximized.

• DiloGroup looks forward to participating in the Techtextil India show 2021.

DiloGroup offers tailor-made production systems from one supplier and will inform at this forum in the German pavillon about its portfolio and the latest equipment developments from fibre opening to the finished felt.

A new, simplified elliptical needle beam drive makes Hyperpunch technology also attractive for standard application. Hyperpunch HαV allows a more uniform stitch distribution in the preneedling process especially in combination with the new needle pattern 6000X. In a complete needling line this felt homogenization process can be improved further by using the new needle pattern 8000X which is a milestone in the needle pattern development process and results in endproduct surfaces with low markings over a wide range of advances/stroke.

The “3D-Lofter” which was first presented during ITMA 2019 in Barcelona offers a wider range of nonwovens applications by exploring the third dimension. A series of single web forming units which work according to the aerodynamic web forming principle deliver defined fibre masses in varied patterns on a base needlefelt. A stress oriented production of technical formed parts resulting in fibre savings or patterned DI-LOUR or DI-LOOP felts are two examples for this technology which explores new application areas for needlefelts.

The 3D-Lofter technology may also be used “inverted” for filling up bad spots in web mats and thus achieves a better homogeneity of e. g. spunlace, thermobond or airlay products. The DiloLine 4.0 concept offer I4.0 modules which not only support the user but also facilitate quality control and maintenance by a maximum data transparency in production and control of operation. The Dilo solutions “Smart Start” for a fully automatic start of the production line or “DI-LOWATT” for energy savings are accompanied by Siemens solutions which can be selected via App or Data Cloud “MindSphere”.

With more than 370 installations delivered to the nonwovens industry worldwide, DiloGroup has the necessary know-how and the complete equipment portfolio to engineer the perfect production line for any product specification. The efficiency of Dilo production lines is the result of long-term research work and experience. Apart from machines for needling technology we offer in cooperation with partner companies also production lines including thermobonding and hydroentangling components.

• Hightech textiles for future-oriented construction projects

Building shells, bridges, staircases, façades ... construction projects are exposed to enormous mechanical loads. Often there are also considerable climatic or environmental influences. This has prompted the increasing use of fibre-reinforced materials in construction projects. After all, besides many other exciting properties, they offer high mechanical rigidity, low weight and excellent corrosion resistance.

Tapes, tubulars, sections and 3D woven textiles by vombaur form the perfect basis for these innovative building materials. The seamless round or shaped woven narrow textiles made of high-performance fibres are extremely loadable because they have neither seams nor welds – and therefore no undesirable breaking points. Their surface properties are identical over the entire length. In challenging tasks, composite textiles by vombaur offer a lightweight solution that is as reliable as it is durable.

Safe and durable solutions for challenging applications
The potential applications for lightweight components in the construction industry are as numerous as the project ideas of the planning and construction teams.
•    Ropes and tensioning elements made of carbon fibre reinforced plastic (CFRP)
•    Reinforcement of building structures made of concrete, steel, wood or other materials
•    Sustainable restructuring of constructions and urban districts for bridges and buildings
•    CFC slats as reinforcements in case of repairs
•    (Filled) GRP pipes made of seamless round woven tubes by vombaur as columns/pillars
•    CFRP sections as steel girder substitutes
•    Hollow profiles with individually designed cross-sections
•    Glass fibre reinforced connecting elements for glazing to minimise expansion differences between the connecting element and the glass
•    Individual light wells

• Harmonized Language Increases Efficiency to Communicate Globally Consistent Descriptions, Production and Testing

EDANA and INDA, the leading global nonwovens associations, jointly announce the launch of the 2021 edition of standard procedures for the nonwovens and related industries.

These Nonwovens Standard Procedures help technically define the nonwovens industry, with specifiers for the properties, composition, and specifications of its products. Offering harmonized language for the industry across the USA and Europe, and recognized by many other individual markets, the procedures offer a way for the nonwovens industry to communicate both across the globe, and within the supply chain to ensure that product properties can be consistently described, produced, and tested.

The harmonized methods contained in the Nonwovens Standard Procedures (NWSP) edition include 107 individual test procedures and guidance documents to support applications across the nonwovens and related industries, and are available on both www.inda.org and www.edana.org.

The 2021 edition includes updated or modified procedures with a numbering structure that makes the document intuitive to search and use. Additionally, each method also includes a page to summarize and track relevant changes made to the document. In an effort to make all methods more consistent, each one is now presented in a format building on the International Standards Organisation (ISO) template, facilitating any future possible submission to ISO in an effort to become a recognized international standard or technical specification.

As in previous editions, the table of contents for the Nonwoven Standard Procedures document includes references to existing related ISO standards, which makes it easier for technicians to choose the most relevant procedure or methods to apply to their product.
