摘　　要：采用差示扫描量热法(DSC)研究了尼龙6(PA6)及其两种复合材料的非等温结晶行为,分别采用Jeziorny法和Mo法对非等温结晶动力学进行了分析,经计算得到相应的非等温结晶动力学参数。结果表明,硫酸钙晶须和硅灰石纤维的加入都能降低复合材料体系的结晶温度;硅灰石纤维的加入可以很好的促进PA6复合材料的结晶,有效的提高体系的结晶速率,而相同含量的硫酸钙晶须对PA6复合材料有一定的阻碍作用,降低了体系的结晶速率。The non-isothermal crystallization behavior of PA6 and two composites was studied by differential scanning calorimetry （DSC）.The Jeziorny and Mo methods were employed to analyze the non-isothermal crystallization kinetics and some important kinetics parameters were obtained by calculate.The results showed that The lower crystallization temperature could reduce by added calcium sulfate whiskers and wollastonite to composite material,while speeds up the crystallization velocity of PA6 and effectively improves the crystallization rate of the content by adds wollastonite,but the equal compositions of calcium sulfate whiskers has certain hinders to PA6 composite system.
