• Composites in the construction industry - The lightweight construction material of the future

Building with fibre-reinforced materials opens up completely new possibilities. In terms of engineering, design, and organisation. This is due, on the one hand, to the excellent properties of fibre-reinforced materials (FRM) and, on the other hand, to the fact that the material – unlike wood or brick, for example – is not machined or processed for its use, but custom-produced.

Excellent properties – in terms of engineering, design, and organisation
Fibre-composite materials offer a whole range of technical properties for innovative and sustainable building:
•    High mechanical rigidity
•    Low weight
•    High corrosion resistance
•    Low material fatigue
•    Low heat transfer coefficient of the plastic matrix
•    Resistance to frost and de-icing salt
•    Good draping capability

In addition, fibre composites offer numerous design options for novel and exceptional new building and maintenance projects:
•    Unique variety of shapes
•    Different structures of the textiles
•    Large spectrum of colours and colour combinations
•    Translucency of the plastic matrix
Thanks to these properties, composites can be used to produce coloured, phosphorescent, thermochromic or – through the use of LEDs or light-conducting fibres permanently integrated into the matrix – luminescent components.

In addition, there are organisational benefits for planning, construction and maintenance work with fibre-reinforced materials:
•    Easier handling and assembly of the far lighter and more flexible components – compared with steel, concrete or wood
•    Faster installation
•    Shorter construction site times in road and bridge maintenance
•    Shorter delivery times
•    Ability to integrate electronic monitoring systems

Individual composite textiles – for every lightweight engineering project
The composites experts at vombaur develop and manufacture woven tapes and seamless round or shaped woven textiles from carbon, glass, flax or other high-performance fibres on special weaving lines for individually specified round and shaped woven textiles – and can therefore offer you the best possible fibre base for every lightweight construction project.

"Regardless of whether it's a new construction or a renovation project, a façade design, a bridge or a staircase – as your development partner for composite textiles, we have plenty of experience with composites for demanding tasks," emphasises Dr.-Ing. Sven Schöfer, Head of Development and Innovation at vombaur. "We develop, create samples and manufacture woven tapes and seamless round or shaped woven textiles – in collaboration with the customer enterprise development teams and individually for the respective projects." This is how novel and unique lightweight components made of high-performance textiles are created for visionary projects.

Belgian textile innovator Devan Chemicals was lauded by Frost & Sullivan for its antimicrobial technology with proven quaternized silane chemistry, known under its trade name as BI-OME®.

RONSE, BELGIUM – The non-leaching attributes of the technology coupled with its ability to reduce microbial mutation make it a potential candidate for textiles where durability and safe human contact are highly valued.

Based on its recent analysis of the European antimicrobial technology for the textile market, Frost & Sullivan recognizes the Belgium-headquartered Devan Chemicals NV (Devan) with the 2020 European Technology Innovation Leadership Award. Devan’s highly relevant antimicrobial technology addresses issues concerning the contamination of PPE and textiles, including the spread of drug-resistant bacteria, viral transmissions, and hospital-acquired infections (HAIs). Its quat-silane technology, due to its non-migrating behaviour, physically punctures the microorganism cell to destroy it without interfering with cell DNA. Notably, it eliminates the adverse effects of leaching antimicrobials while providing high efficiency in the range of 99.9 percent to 99.99 percent, even after multiple washes.

"By providing non-migrating antimicrobial technology for the textile industry, Devan plugs the safety and performance gaps inherent in current inorganic and organic antimicrobial agents. Its antimicrobial technology, unlike silver- or triclosan-based technology, comprises non-migrating monomers and prepolymers such as organo-functional silane," said Monami Dey, Industry Manager, Frost & Sullivan. "The organo-silane polymers are covalently bonded and polymerized to the textile surface as a coating via padding, exhaust, and spraying techniques. The coating forms a non-leaching reactive surface and destroys the microbes on contact, without releasing harmful components into the environment."

Devan CEO Sven Ghyselinck is very happy with the award: “The best practice award is a nice recognition of the hard work we did in the last 6 months to evaluate the performance against viral activity. It’s great to see our efforts didn’t go unnoticed.”

Earlier this month Devan published new test results confirming the high performance virus-reducing capabilities of its BI-OME fabric coating technology on both unwashed and intensely washed fabrics. The Belgian company has worked closely with a series of international third party laboratories to test different fabric substrates against a wide range of enveloped viruses. Before washing, samples treated with Devan BI-OME score very good to excellent (99% and higher according to ISO 18184) results on virus reduction. Different substrates, like polyester, cotton and polycottons, were exposed to enveloped viruses like SARS-COV-2 (known to cause COVID-19), Feline Corona, Vaccinia (the EU standard for enveloped viruses) and Porcine Respiratory viruses. After 30minutes, BI-OME already reduced 99.96% of the activity of SARS-COV-2.

After washing, a decrease in virus reduction performance of coating technologies is normal and expected. However, BI-OME is confirmed to deliver only a minimal reduction, retaining up to 98.5% virus reduction even when the fabric is washed 25 times.

"Devan is working towards sustainability and green chemistry. For instance, its technology does not contain any harmful solvents such as formaldehyde or polychlorinated phenols and fulfills the regulatory obligations of the EU BPR," noted Dey. "Its commitment to promoting sustainability in textile finishes with a strong focus on GMO-free, kosher, as well as halal certifications, and recyclability has given the company an edge in launching new products at an accelerated pace to match customers’ most pressing concerns and demands."

One of those innovations is BI-OME NTL (natural), a natural, bio-based antimicrobial solution that guarantees an optimal freshness and hygiene for textiles. The active ingredient is the well-known Linseed oil, obtained from the dried, ripened seeds of the flax plant. The active ingredients in BI-OME NTL are GMO free, Halal, Kosher and recyclable.

Lectra has leveraged more than 10 years of experience in connected manufacturing to offer Versalis®, an innovative digital solution designed to cut leather without compromise on quality. Featuring a powerful automatic nesting system for overall improvements in efficiency, the fully automated solution enables automotive leather suppliers to cut costs, improve productivity and minimize waste while also establishing a pathway to value-added Industry 4.0 processes.

Currently, almost 90% of leather used for automotive applications is cut using manual die presses, which require designers to build a physical prototype and finalize the design through trial and error. Lectra offers a fully digitalized leather solution from prototyping to cut parts—when used in combination with Lectra’s 3D prototyping and pattern-making software, Versalis digital leather cutting solution enables a 12-16 week reduction in development and launch cycles for vehicle seating models.
During the leather-cutting phase, the latest release of Versalis LeatherSuite allows automotive leather suppliers to achieve up to 15% greater productivity. Lectra’s end-to-end automotive leather offering furthermore guarantees optimal uptime through an extensive worldwide support network of field engineers and technical experts.
"Lectra focuses on a consultative approach that allows it to fully understand the customer’s needs before building a solution comprising software, hardware, consulting, training, and after-sales support,” said Frost & Sullivan Industry Analyst Kamalesh Mohanarangam. "Lectra’s equipment is fitted with more than 200 sensors that predict failure and immediately report issues to its call centres. This product feature and service has resulted in 98% uptime and very fast mean time to repair."

Although digital leather cutting solutions are an investment, leather cutters and Tier-1 suppliers have begun to recognize the value of these products. On average, Lectra’s solutions help customers achieve up to 7% savings on leather compared to manual die-press methods by minimizing human error and variability in the cutting room. A benchmark test of leather trim cutting for door panels demonstrated a 3.5% gain in material made possible by Versalis’ superior nesting capabilities compared to the customer’s yield using manual nesting with die press machines, representing potential savings of €9 million per year.
Versalis is the fruit of significant R&D investment for the company, which has always made re-investment of capital a priority. As part of a transformational plan, Lectra spent more than €50 million in investments between 2011 and 2015. With Lectra’s new strategy focusing on supporting their customers’ transition to Industry 4.0 standards, Lectra will increase the share of revenues dedicated to R&D to 10% for the period from 2017 to 2019, representing a rise of about 50% between 2016 and 2019.
