This paper revealed delaminations, fiber fractures, splits and interfacial debondings, etc., in the CFRP internal laminates....

    This paper debated bearing damage in CFRP laminates around loaded hole under static and fatigue load. It studied damage initiation and propagation by the "deply technique", "X-ray radiographs" and "scanning electron microscope method". The testing program was also performed to study the effect of temperature and moisture to bolted static bearing strength and its fatigue life. This paper revealed delaminations, fiber fractures, splits and interfacial debondings, etc., in the CFRP internal laminates. The damage features were recorded with charts and photographs. The testing results showed that fiber bundle fraeture initiated on the internal laminates and progressed toward the exterior laminates with increasing load. The results also showed bearing areas around the loaded hole, had relation to fiber orientations of each laminate. The damage specimens were detected and analysed to study damage mechanism,
