Increasing the long-term durability of bio-hybrid fiber-composite materials through plasma treatment

Through the unification of natural fibers and conventional carbon fibers in bio-hybrid fiber composites, good damping properties, low material costs and sustainability can be combined with unparalleled mechanical strengths and rigidity. Bio-hybrid fiber composites thereby have a high potential for application in, amongst other things, the automotive and sporting goods sectors. Up until now, however, insufficient long-term durability has hindered the use of bio-hybrid fiber-composite materials under challenging climatic conditions such as high humidity or strong temperature fluctuations.

Crack-penetration plasma source concept for the homogeneous, comprehensive treatment of individual fibers and fiber composites

As part of the internal research project “MEF-Bio-HyFi-LEPLAS”, we are developing, in collaboration with the Fraunhofer Institute for Surface Engineering and Thin Films IST, a procedure for the optimized plasma treatment of natural-fiber fabrics, in order to increase the long-term resistance of bio-hybrid fiber-composite materials against, for example, temperature fluctuations, moisture penetration or UV irradiation. The aim is the development of a cost-effective and environmentally friendly procedure for fabric treatment which can be easily integrated into existing process chains and which significantly improves the long-term durability of the material.

As a result, new application possibilities are being created for bio-hybrid fiber composites, which we present exemplarily by means of demonstrator components for the sporting goods sector and the automotive manufacturing industry.
