摘要：

Matrix crack growth behaviour under quasi-static and mechanical fatigue loadings has been studied in quasi-isotropic (0/90/ - 45/ + 45)(s) GRP laminates. Derailed experimental observations were made on the initiation and growth of individual cracks in +/- 45 degrees and 90 degrees plies. Degradation of elastic properties of the laminates due to matrix cracking was observed and recorded. The quasistatic results were compared with baseline data from a crossply (0/90)(s) laminate. Distinctly different crack growth behaviour was observed in quasi-isotropic laminates under quasi-static and fatigue loadings, suggesting a strong influence of load history. A higher density of +/-45 degrees cracks and hence greater stiffness reduction appear to be the characteristics of fatigue damage in quasi-isotropic laminates. (C) 1997 Elsevier Science Limited.
