Experimental study on compressive properties after high velocity impact of composite laminates
摘要
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 im-pacted 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 ve-locity 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 bal-listic limit.The residual compressive properties of laminates impacted at quarter position is worse than the center po-sition.关键词
