Fatigue Damage Mechanisms of Advanced Hybrid Titanium Composite Laminates

Abstract

The objective of this thesis is to compare the mechanical response of this advanced Hybrid Titanium Composite Laminates (HTCL) to the first generation material. Specifically, the effect of a stronger bondline at the titanium/ Polymer Matrix Composites (PMC) interface in constant amplitude fatigue will be investigated, particularly in the event that titanium ply cracking induces the delamination. Therefore, the focus of this research is to closely monitor and analyze the damage progression of this modified HTCL during fatigue testing to ultimately determine the specific damage evolution and mechanisms present. While tension-tension fatigue is conducted and compared to the previous HTCL testing, tension-compression fatigue is conducted on both laminates in this research as delamination effects are enhanced under compressive stresses.
