摘　　要：The main objective of this study is to investigate the dynamic processes of the interlaminar fracture of the glass woven fabric reinforced polycarbonate composites through in-situ observation of specimen under mode Ⅰ loading by SEM and stereomicroscope. The results show that the evolution processes of interlaminar damage consist of micro-crack initiation, growth and coalescence and advance forward of the main crack tip. The mode of crack propagation in fabric composite observed here seem to be the propagation along interface, interface change and fabric separation.The main objective of this study is to investigate the dynamic processes of the interlaminar fracture of the glass woven fabric reinforced polycarbonate composites through in-situ observation of specimen under mode Ⅰ loading by SEM and stereomicroscope.
