Abstract: Composite laminates were a new kind of structure material with high strength-to-weight
ratio and high stiffness-to-weight ratio. It was very important to analyze and simulate the mechanical
behaviors posite laminates. According to the papers and research reports on mechanics property
posite laminates at home and abroad in the last two decades, the paper is summarized on the
mechanics property posite laminates especially about the posite laminates. A
progressive damage analysis method based on the mechanics property of unidirection lamiantes was
widely used in the study of static and fatigue behaviour posite laminates. The main problems in
the study of posite laminates
