In May 2017, the "Center for Textile Lightweight Engineering" started its operation at a new technical center with the size of 1.500 sqm.

The following technologies for processing carbon fibre waste into nonwovens are available in a semi-industrial standard:

 

  • Cutting- and tearing technologies to transfer dry textile waste of high-performance materials (especially made of carbon fibres) into applicable fibre layouts for further textile processing
  • Carding technologies for processing of high performance fibres into mechanically bonded nonwovens, realized by using carding machine, cross-lapper, needle loom and/or stitch-bonding machine (working width 100 cm)
  • Random web technology for processing of high performance fibres into mechanically bonded nonwovens, realized by using airlay random carding machine, needle loom and/or stitch-bonding machine (working width 100 cm)

Another focus is set on formation of sliver- or thread-like unidirectional structures using recycled carbon fibres.

In addition to manufacturing textile semi-finished materials, the production of specimen and prototypes made of fibre-reinforced composites with thermoplastic or thermoset matrix is possible in following steps:

 

  • Hand lay‑up
  • Pressing
  • Resin Transfer Molding (RTM)
  • Vacuum Infusion (VAP® License)
  • High Pressure Resin Transfer Molding (HP-RTM)

An integrated test laboratory, which is constructed for the specific requirements of textile lightweight structures, completes the “Center for Textile Lightweight Engineering”. Therefore, accredited tests of high performance fibres, textile fabrics or composites can be carried out on site.
