摘　　要：利用分离式霍普金森压杆(SHPB)实验装置,在常温和低温条件下对改性聚酰胺1010(PA1010)分别进行了650/s、1 350/s、2 300/s和3 300/s四个应变率的动态冲击压缩实验。结果表明:改性PA1010在常温和低温条件下均存在明显的应变率效应,其中低温下的应变率效应更为显著;改性PA1010的动态压缩力学性能存在明显的温度依赖性,同一应变率条件下,材料的低温应力值较常温下显著提升,另外材料在低温条件下还表现出良好的冲击压缩韧性。The dynamic mechanical properties of modified polyamide 1010（PA1010） under four strain rates（650/s, 1 350/s, 2 300/s and 3 300/s） were studied by split hopkinson pressure bar（SHPB） experimental technique at normal and lower temperatures. The results indicate that there is an significant strain rate effect for modified PA1010 at normal and lower temperatures（especially at low temperature）. Moreover, the dynamic properties of modified PA1010 has obvious temperature dependence. Under the same strain rate, the stress value at lower temperature is much higher than that at normal temperature, and the modified PA1010 also shows excellent impact compression toughness at low temperature condition.
