摘　　要：通过FTIR、DSC、XRD等研究了环氧树脂E44对低熔点聚酰胺6(LPA6)复合材料的结晶行为、力学性能、熔体流动性能及耐热性能的影响。结果表明:随着环氧树脂E44含量的提高,复合材料的拉伸强度、弯曲强度和缺口冲击强度均先增大后减小,在E44含量为3%时,均达最大值,分别为89.41 MPa、95.06 MPa和7.98 kJ/m2。复合材料的维卡软化点先减小再增加,当环氧树脂用量为7份时,达到最小值64.1℃。The effects of epoxy resin E44 on crystallization behavior, mechanical properties, the melt flow properties and thermal properties of low melting point Polyamide 6 （LPA6） composites were investigated by FTIR, DSC, and XRD. The results show that： the tensile strength, bending strength and notched impact strength of composites increase firstly and then decrease with the increasing of the content of E44; and when the content of E44 is 3%, the tensile strength, bending strength and notched impact strength of composites can reach to the maximum, which are 89.41 MPa, 95.06 MPa and 7.98 kJ/m2 respectively. Vicat softening point of composites decreases firstly and then increases; when the content of E44 is 7 phr, the softening point reaches to minimum, is 64.1℃.
