Fatigue Crack Growth Tests on Glass fibre Reinforced Polymer Matrix Composite

摘要

E-glass fibre reinforced polyester matrix composite was investigated, which was made by pullwinding process. Round three point bending (RTPB) specimens were tested under quasi-static and mode I cyclic loading conditions. Load vs. displacement (F-f), load vs. crack opening displacement (F-v) and crack opening displacement range vs. number of cycles (ACOD-N) curves were registered and analysed, rnterfacial cracks were caused the final longitudinal fracture of the specimens under quasi-static and cyclic loading conditions.
