通过熔融共混法制备了不同CaCl2质量分数的CaCl2/环氧树脂(E51)/尼龙6(PA6)复合材料,利用DSC、流变仪、FTIR和电子拉伸机等研究了不同CaCl2质量分数下CaCl2/E51/PA6复合材料结晶行为及其力学性能,并研究了其受限机制.力学性能结果表明,随着CaCl2质量分数的增加,CaCl2/E51/PA6复合材料拉伸强度呈现出先增大后减小的趋势,当CaCl2质量分数为3％时,复合材料拉伸强度达到最大值82.67 MPa,是纯PA6的拉伸强度(60.5 MPa)的1.366倍,而结晶行为结果表明,增加CaCl2的质量分数,CaCl2/E51/PA6复合材料的成核温度、晶体生长温度、熔融温度及玻璃化转变温度均向低温方向移动,成核密度和成核速率也逐渐减小,结晶能力下降,结晶度由原来25.22％变为9.90％.
