摘要
本文通过低速冲击试验,研究了芳纶纤维与玻璃纤维两种用于机匣包容环的复合材料在不同冲击能量下的破坏形式和失效机理。试验结果表明,当冲击能量为36 J时,芳纶纤维和玻璃纤维复合材料的吸能能力相近,两种复合材料损伤以基体开裂为主。当冲击能量增加至117 J时,复合材料的破坏形式主要为纤维拉伸断裂、分层损伤,在高能量冲击下,芳纶纤维复合材料通过纤维断裂以及分层展现更优的吸能能力。
In this paper,the damage forms and failure mechanisms of two kinds of composite materials,aramidfibres and glassfibres,used for the casing containment ring under different impact energy are investigated through low-speed impact tests.The test results show that when the impact energy is 36 J,the energy absorption capacity of aramidfibre and glassfibre composites is similar,and the damage of the two kinds of composites is dominated by matrix cracking.When the impact energy is increased to 117 J,the failure forms of the composites are mainly in the form offibre tensile fracture and delamination damage,and the aramid fibre composites show better energy-absorbing ability through fibre fracture and delamination under high energy impact.
