Fatigue behaviour of FLAX reinforced composites

The present study focuses on the characterization and evaluation of fatigue behaviour of flax-epoxy composites. A better understanding of this behaviour allows the prediction of long-term properties to assess the viability and long-term durability of these materials. The purpose of this work is to systematically study the tension-tension fatigue behaviour of flax fibre composites for five textile architectures and four laminate configurations, which are used in a wide range of applications. The fibre architecture was found to have a strong effect on the fatigue behaviour where higher strength and modulus combinations have a delayed damage initiation and increased fatigue life as well as a reduced damage propagation rate and higher energy dissipation in the early stages.
