复合材料冲击时拉、压性能和静荷时一样是明显不同的。为此,我们进行了三种复合材料的拉伸冲击试验,分析了实验的现象和结果。特别强调了试件制备中的一些问题。 Composite materials when the impact of pull, pressure performance and static load is obviously different. To this end, we conducted three kinds of composite tensile testing, analysis of the experimental phenomena and results. Particular emphasis is placed on some issues in the preparation of test pieces.
