Durability of Natural Fiber-Reinforced Bio-Polyamide Composites for the Electronics and Automotive Industries

This subproject will investigate the durability of natural-fiber-reinforced engineering bioplastics (various bio-polyamides) specifically for the electronics and automotive sectors. Materials will be developed for use in components subjected to high mechanical and thermal stress (engine compartments, battery housings, etc.). To this end, composites made of bio-polyamides and natural fibers must first be produced, with a bio-based content of at least 80%. The natural fibers (regenerated cellulose fibers) serve not only as fillers but are specifically used to enhance mechanical properties.

Suitable additives are used to improve durability and processing properties. Furthermore, relevant durability factors and process influences are identified in close collaboration with project partners from the electronics, automotive, raw materials production, and compounding sectors. The aged composites are to be characterized in terms of properties such as odor, mechanical properties, and fatigue. The project will also investigate how the fiber content affects the aging behavior of the composites and the sample components manufactured from them by the project partners.
