Abstract
Raman spectroscopy was used to monitor the interfacial behavior in graphite/epoxy single filament composites. The effect of thermal and hydrothermal exposure at 100°C on the interfacial properties was also monitored. Hydrothermal exposure caused a 50% reduction in the ability of the interface to withstand shear stresses. It was found that the degradation is due to failure of the interfacial bonds, and that the interfacial bonds fail due to radial tensile stresses created at the interface resulting from matrix swelling upon water absorption.
