编织型复合材料的冲击及冲击后压缩强度的试验研究

The experimental research of impact and CAI of woven composite

通过对冲头进行设计 ,和采用多通道的数据采集系统 ,得到较为详尽的冲击响应的过程 (包括冲击力 ,试件的正背面响应 ,离冲击点不同距离的响应 )。并且本文还进行了冲击后的压缩试验 ,对编织型复合材料在不同冲击能量下的压缩破坏载荷 ,及损伤后不同位置的响应进行了记录和讨论 。

The current impact experiments have not record the response of force and strain in impact process. Elaborate response process of impact for woven composite including impact force of impactor, strain response of different position in the specimen is observed by the special design of impactor and multichannel collection system. The compression experiment after impact is discussed in the paper. Also, the compression damage force after different impact energy and the strain response of different position are presented. It is a satisfying method for experimental research to find the strain distributing in impact and CAI, as well as the compression strength of CAI.
