摘要: 本文通过高速冲击后压缩试验,探讨了复合材料层合板在受到不同速度、不同位置冲击后的压缩承载行为、破坏形式和失效机理。试验结果显示,不同位置冲击层合板的破坏载荷和损伤形式存在较大差别,中间位置冲击层合板的破坏形式主要是分层屈曲破坏,边缘位置冲击层合板则是压缩和整体屈曲破坏。层合板高速冲击后压缩破坏载荷随着冲击损伤面积的增大而减小,并随着冲击速度的增大而先降低后增大,破坏载荷在冲击速度略高于弹道极限时最低。与中间位置被冲击后相比,层合板边缘位置被冲击后的剩余压缩性能更差。

Abstract: In this paper, the compressive behavior, failure mode and failure mechanism of composite laminates after high velocity impact were studied by compressive tests. The experimental results show that the failure load and the failure mechanism of laminates impacted at different positions are different. The failure mode of laminates impacted at center position is mainly layered buckling failure, while the failure mode of laminates impacted at quarter position is compression and overall buckling failure. The compressive failure load of laminates impacted by high velocity is reduced by the increase of the damage area. As the impact velocity increases, the compressive failure load decreases and then increases. The failure load is minimized when the impact velocity is slightly higher than the ballistic limit. The residual compressive properties of laminates impacted at quarter position is worse than the center position.

Key words: high velocity impact, compression after impact, composite, failure mechanism
