Recycling & Sustainability

Recycling and sustainability play a major role in material development. The Fiber Institute is investigating the use of recycled carbon fibers on the one hand and the use of bio-based, degradable and recycled materials for fiber development on the other. The aim is to create efficient and environmentally friendly alternatives to conventional materials that protect resources and reduce environmental impact. The reuse of used carbon fibers is ecologically and economically particularly sensible due to the high energy content during production. Due to their fineness, brittleness and embedding in the polymer matrix, the textile processing of the longest possible fibers is particularly demanding. Therefore, the institute is working successfully in cooperation with project partners on the characterization of processed short and staple fibers. Furthermore, FIBRE is investigating the development of rCFPEEK compounds of pure origin for aircraft construction and the use of rCF nonwovens in aircraft interiors. In the field of research and development of new fibers, a particular focus is on the use of bio-based and biodegradable polymers as well as the use and development of recycled materials. Materials such as polylactide, polybutylene succinate or alginate are used for this. The aim is, for example, to develop yarns at a technical level, customized degradability or sustainable filter fibers. More…
