Abstract : The fracture behavior of thermoplastic poly(ethylene terephthalate) reinforced with short E-glass fiber was investigated, using fractography and a fracture mechanics approach. The observed microstructures, crack propagation, and the stress-rupture lifetime data indicate a sudden breakdown induced by far-field effects. The critical damage appears to be correlated with a ductile-to-brittle transition of matrix fracture. The calculation of fracture toughness for various fiber orientations indicates that the fiber pull-out energy is the dominant term in the case in which the fiber orientation is perpendicular to the notch tip. jg p4
