Multiple amplitude testing method for detection of local damage evolution in bast fiber-reinforced polymers

New resource efficiency requirements create new demands on the materials used. Conventional fiber-reinforced polymers with a thermoset matrix and synthetic reinforcing fibers are creating significant challenges for material recycling and thus for sustainable application. Natural fiber-reinforced polymers with thermoplastic matrix offer high recycling potential as well as lower primary energy consumption in the production of composite material. In particular, natural bast fibers based on flax and hemp can be efficiently cultivated in European agricultural areas, eliminating long transport distances. However, natural bast fibers show a considerable variation in material properties compared to synthetic fibers. The growth condition of the fiber material directly affects material properties such as fatigue strength and damage evolution under fatigue loading.
