Abstract (englisch):

Carbon fibre reinforced polymer (CFRP) is widely used across different industries, mainly aviation, marine, automotive, sports equipment, and many more. This is attributed to its outstanding high strength-to-weight ratio compared to other materials such as metals. In addition, this material also features design customizability to fit various applications, which makes it one of the most versatile materials today. In real-life applications, CFRP structures are subjected to fatigue loading. The material response towards this loading is very complex. This is due to the evolution of damage within the material that occur through various failure mechanisms. The intricacy of fatigue damage in CFRP material is also contributed by the individual failure mechanisms and the synergy effects by these failure modes that occur concurrently at the microscopic level. Due to this complexity, macroscopic and microscopic material level response knowledge is required to comprehensively understand fatigue
damage in CFRP. However, this crucial knowledge is not easily obtainable from standard testing alone.

This thesis discusses the analysis of damage methods for unidirectional (UD) CFRP under fatigue loading through experimental and modelling work. ... mehr
