摘要：

The fracture behavior of a glass-fabric-reinforced epoxy composite has been investigated experimentally. Load-displacement curves for single-edge-notched specimens were obtained on an MTS system and the J-integral evaluated through its energy rate interpretation. J//c, the critical value of the J-integral, obtained directly for a//0/w greater than 0. 4 and that obtained through an extrapolation procedure for a//0/w less than 0. 4 compare quite well. J//c appears to be independent of crack length for specimen widths between 15 and 45 mm. J//c for plus or minus 45 degree specimens is less than half that for 0/90 specimens.
