摘要
采用SHPB冲击试验装置,对AF/ZF(AramidFiber/ZylonFiber)混杂纤维防弹复合材料进行了横向冲击试验,获得了不同混杂比的混杂复合材料的载荷历史与位移历史,进一步分析了其破坏过程和能量吸收特性。所得结果与不同混杂比的AF/ZF混杂纤维复合材料实弹靶试吸能特性变化趋势相似。结果表明,进行不同混杂比AF/ZF混杂纤维复合材料的横向冲击试验对预测实弹冲击的破坏吸能有参考价值。
The transverse impact test of AF/ZF (Aramid Fiber/Zylon Fiber) hybrid composite was performed by SHPB (Split Hopkinson Pressure Bar). The loading history and displacement history of the composites with different hybrid ratios were obtained, from which the failure process and energy absorption characteristics were further analyzed. The change trends of BPI (Ballistic Performance Indicator) data obtained from SHPB are similar to those of the ball firing data, indicating that the transverse impact test on AF/ZF hybrid composite has a certain reference value to predict the energy absorption of composites target in the ball firing.
