The Effect of Marine Environment on the Compression Behavior and Fatigue Loading of CFVE Sandwich Structures
Abstract
In this research, developing a quantitative understanding of the behavior of Carbon Fiber Vinyl Ester based composites subjected to compression loading and its degradation due to coupled sea water environment. Damage progression will be evaluated by periodic and targeted load reversals and integration of the measurements with macroscopic true stress-strain behavior. Damage accumulation zones will be identified from spatial strain maps using 3d-DIC and effects of local microstructure using high resolution X-ray tomography. This research involves three tasks: Characterization of the compressive behavior of CFVE composites and sea water effects: CFVE sandwich structure tensile fatigue behavior exposed to sea water: and Damage evolution of CFVE subjected to cyclic loading and sea water effects.In this research, we will develop a quantitative understanding of the behavior of Carbon Fiber Vinyl Ester based composites subjected to compression loading and its degradation due to coupled sea water environment.
