摘要
Abstract
Polyamide 6(PA 6)/carbon fiber composites toughed with epoxidized silicone rubber(ESR-5)/methyl silicone rubber(PDMS)compounding system were prepared through melt blending,and the effect of epoxy content on the me-chanical properties,impact properties,heat resistance,and microstructure of PA6 composites was investigated.The re-sults indicated that when there were 10 phr ESR-5 and 10 phr PDMS in the compounding system,the interface force be-tween PA and silicone rubbers could be by in situ grafting reaction,thus enhancing the impact resistance and damage re-sistance of the composites.This resulted in an increase in the notched impact strength by 73.6%,178.0%and 196.8%at 23,-20,and-60℃,respectively,compared to the composites without toughening,exhibiting an excel-lent impact resistance in low temperature environment.This also minimized the impact of introducing elastomers to the reduction in the mechanical properties of the composite system.Meanwhile,the thermal stability of the composites was improved.The ESR-5/PDMS toughening system provides a feasible solution for the applications of carbon-fiber-rein-forced PA6 composites in low temperature environments.关键词
