• Glass fiber textiles for helicopter type H145
• First ever material supply for primary structural components in the aerospace segment

Since August of this year, SGL Carbon delivers two special glass fiber textiles, so-called non-crimped fabrics, for the new version of helicopter model H145 from Airbus Helicopters. These materials are used in the new, especially efficient five-blade rotor. Developed in close collaboration with Airbus Helicopters, the material has been qualified for the application for the next years to come.  

Thanks to their unidirectional fiber orientation, the fabrics are extremely resistant, providing optimal support for the new geometry of the especially long H145 rotor blades. The fabrics are manufactured at the SGL Carbon site in Willich near Düsseldorf in a multi-stage process and delivered to Airbus Helicopters in Paris.  

“The order emphasizes our growing presence in the aerospace business. With the fabrics for Airbus Helicopters, we have realized, qualified, and started serial production for a material concept for primary structural components for the first time,” underscores Dr. Andreas Erber, Head of the Aerospace segment in the business unit Composites – Fibers & Materials at SGL Carbon.

The current deliveries are part of a framework contract with Airbus Helicopters, intended to gradually intensify collaboration. Besides the current development of materials for helicopter components, Airbus Helicopters and SGL Carbon have worked together in the area of component material processing for Airbus group aircraft doors for years. In addition, Airbus and SGL Carbon are jointly involved in various associations and research projects in the area of components, such as Carbon Composites e.V.

• R-TWO™ plays a major role in ISKO™’s SS21 fabrics collection, featuring throughout all of ISKO™’s inspirational and forward-looking denim offer.

ISKO denim mill has recently welcomed to its family of innovations its most revolutionarily responsible yet: R-TWO™. This concept was essential to the development of the SS21 fabrics collection featuring an across-the-board employment of the “reused and recycled” program throughout ISKO™’s denim offer, confirming once again the company’s commitment to environmental and social responsibility.

Preventing over-sourcing, avoiding waste.

In keeping with ISKO’s Responsible Innovation™ approach, this concept deals with the most critical matter that apparel supply chains are currently faced with: using more than what actually needed. ISKO R-TWO™ reduces the amount of raw material sourced by relying on a blend of reused cotton and recycled polyester, improving sourcing efficiency throughout the entire field-tofabric production. This cutting-edge program effectively tackles over-sourcing – the leading issue when it comes to waste hierarchy.

Processing resources

During the processing of raw cotton into yarn, for every 100 kilos of cotton approximately 10% is lost. ISKO collects it and prevents it from becoming waste, adding it back into the spinning process obtaining cotton that is fully traced, documented and audited. This verification process has been invented by ISKO in partnership with its yarn supplier Sanko, offering full clarity into the traceability of reused cotton from field to fabric. It is also certified with the Content Claim Standard – or CCS – of the Textile Exchange.

On the other hand, recycled polyester comes from clear plastic bottles or, alternatively, it can come from other certified waste: in either case the source material is collected, sorted, stripped of labels and caps, and cleaned. This material is then ground into plastic pellets that can then be re-spun into new fiber filaments, which are then blended with the reused cotton to create R-TWO™ fabrics. A major asset of employing recycled polyester is the energy required to produce it, which is less than that required to manufacture virgin polyester. By using more recycled polyester, ISKO effectively reduces its dependence on petroleum as a raw material, ultimately reducing the overall carbon footprint of ISKO™ fabrics.

Depending on the content percentages, for the recycled polyester ISKO can provide either the Recycled Claim Standard (RCS) or Global Recycled Standard (GRS) certifications, both of which track the recycled raw material through the supply chain from input to final product to verify its integrity.

Rethinking innovation

The R-TWO™ program was developed to keep on delivering a futuristic and innovative sustainable approach, one where ISKO rethinks its sourcing strategies and refuses to source more raw materials than what actually needed. The objective? Improving, more than ever before, the environmental performance impact of yarn to fabric production, to do better for the planet and its people. Note for pictures: R-TWO™ fabrics played a key role in the development of “Light on the Land”, the new ISKO™ x Miles Johnson collection incorporating fashion and responsibility.

• Reduction of material usage by up to 50 percent through innovative draping strategy in the production of fibre composite materials

In fibre reinforced plastic (FRP) production, stamp forming is one of the most economical processes for automated large-scale production, e.g. in the BMW i-series. However, the current processes are susceptible to draping errors and a high proportion of waste. An innovative process developed at the Institut für Textiltechnik of RWTH Aachen University, short ITA, can now significantly reduce the scrap rate and reduce the waste rate of high-priced reinforcing textiles, such as carbon fibre textiles, by up to 50 percent. Sven Schöfer from ITA achieved this effect with his work "Development of a textile-based material feed to increase the preform quality during stamp forming of reinforcing layers". On 10 September 2019, he won the third AVK Innovation Prize in the "Research and Science" category at Composite Europe in Stuttgart, Germany.

Current process
In stamp forming, clamping grippers are usually used in industry to feed the stacked individual layers to the forming process and position them on the lower tool via a clamping frame or hold-down device. Due to the clamping grippers, the cutting proportion of cost-intensive reinforcing textiles is high, as additional material at the textile edge is necessary with clamping systems. Other approaches to feeding the reinforcing semi-finished product during forming and simultaneously improving the draping quality are also not economical: they are usually only designed for certain textile cuts, cannot be automated, are prone to errors or are expensive special solutions.

There is currently no system in the industry that can apply retention forces along a final contour with low waste and remains flexible in terms of geometry.

Innovative approach of Sven Schöfer
The innovative process developed by Sven Schöfer works with a detachable textile joint, a so-called tufting seam. It allows the single layers to slide off during the forming process under a retention force dependent on the seam design.

This reduces or completely eliminates draping errors in previously critical areas, even with complex preform geometries. This leads to a significant increase in preform quality and a reduction in scrap rates. The process is also highly efficient, as tensile forces can be applied to any component geometry on near-net-shape blanks. This reduces the material input by up to 50 percent.
