摘要: 采用自由落体冲击设备, 对两种不同尺寸不同铺层顺序的T300/BMP-316复合材料层合板进行了详细的低速冲击损伤试验研究, 同时应用作者以前发展的复合材料层合板逐渐累积损伤分析方法对层板的冲击过程进行了模拟.结果表明, 几何尺寸对层合板的冲击损伤投影面积有较大的影响, 而铺层顺序对冲击损伤投影面积影响不大, 但对层合板的冲击损伤形状会有一定的影响.

Abstract: The experimental research of low speed impact damage has been carried out on composite laminates with different geometries and layer direction angle,and the impact process was simulated by the progressive damage method.The geometries of composite laminates have much effect on the impact damage projected area.The layer direction angle of composite laminates has little effect on the impact damage projected area,but it has influence on the impact damage figure.
