At the K 2016, the researchers of Institut für Textiltechnik of RWTH Aachen University will be presenting their latest research results in hall 6 booth D76, a group stand of the German State of North Rhine-Westphalia (NRW):

Process chain for hybrid yarn based thermoplastic fibre reinforced composites

Hybrid yarns or composites made from hybrid yarns so far have had little impact on the market due to a lack of confidence in the material. Therefore ITA is conducting research along the complete process chain. The display illustrates the advantages of a hybrid yarn based process chain for thermoplastic composites showing hybrid yarns, hybrid yarn weaves and consolidated parts (s. picture 1 “Process chain for hybrid yarn based thermoplastic fibre reinforced composites”, source ITA):

Parts can be produced directly from the hybrid weaves compared to the established process (film stacking and subsequent thermoforming).

The potential for short cycle times and mass production is given due to short melt flow paths of the thermoplastic matrix.

Functionalization of the parts using injection moulding is possible.

The target group is industries with large scale production such as the automotive industry. The main advantage is the short cycle time resulting in low production costs.

Car roof segment based on integral reinforced fabrics

For the first time, a car roof segment was completely produced from integral reinforced fabrics (s. picture 2 “Car roof segment based on integral reinforced fabrics”, source: ITA). The textile architecture according to load paths allows the reduction of component weight by a higher exploitation of the fibre properties.

Production costs will decrease owing to less waste and less process steps during preforming because the single integral reinforced layers are manufactured in a single step by open reed weaving.

Textile composition of a fuselage

An open reed weave was used to reinforce holes and inserts. The stringers in the lower section were produced via 3D weaving. The stringers in the upper section were manufactured as tailored non crimp fabrics. The frame was produced by overbraiding (s. picture 3 “Textile composition of a fuselage”, source: ITA). Many ITA technologies can be shown in the demonstrator. The textile composition of a fuselage is most interesting for aerospace and automotive. ITA demonstrates its expertise in the evaluation of technologies considering the whole process chain at its main exhibit.
