摘　　要：通过偏光显微镜和差示扫描量热仪(DSC)研究了碳纤维(CF)和滑石粉对聚酰胺6(PA6)结晶行为的影响。结果表明,CF 的加入在 PA6和 CF 的界面诱发横品,CF 和滑石粉在 PA6基体中起到了异相成核作用,改变 PA6的成核机理和晶体生长方式,提高了起始结晶温度和结晶速率。结晶速率随着等温结晶温度的升高而下降。当冷却速率增大时,起始结晶温度下降,结晶度增大。Polarizing microscopy and DSC were powder on the crystallization of polyamide 6 used to investigate the effect of carbon fiber and talc It showed that carbon fiber could induce transcrystallization of PA6. Carbon fiber and talc powder promoted the nucleation in matrix, changed the crystal growth mode, and increased the crystalline rate and the onset crystallization temperature. The crystallization rate increased with increasing crystallization temperature. When the cooling rate increased, the onset crystallization temperature was elevated and the degree of crystallinity was also enhanced.
