英文摘要	The variation of conductivity of polyamide-6 (PA6) filled with stainless steel fiber (SSF) and carbon nano tube (CNT) under high pressure and strain rate was studied experimentally by using one-stage light-gas gun. The experiment scheme was designed and optimized multiple times to obtain the best scheme that could reflect the relation between the stress and resistance. In order to understand the dynamic process better, ANSYS/LS-DYNA was used to analyze the dynamic mechanical property of conductive ploymer composite. The experiment results indicate that the experiment scheme and resistance measurement device are effective under high pressure and strain rate, and the relationship between the high pressure stress and the resistance of the conductive polymer can be reflected well. In order to explain the inner link between impact load and resistance effect, the single electron motion was analyzed to establish the dynamic conductive model of the conductive polymer composite, and the resistance phenomenon of PA6 filled with CNT, SSF composite system subjected to impact load was explained. The results show that the resistance of the composite is in violent evolution under high pressure and strain rate.; EI; 0; SUPPL. 2; 205-213; 32
