摘　　要：采用双辊开炼机将玄武岩纤维(X)、碳纤维(C)与聚丙烯(PP)、乙烯-乙酸乙烯酯共聚物(EVA)进行熔融共混,制备了PP/EVA/X/C复合材料。研究了X与C复配比例对PP/EVA复合材料力学性能的影响,并探讨了优化后的复配比例对PP/EVA复合材料加工性能、热性能的影响以及复合材料的微观结构情况。结果表明:当X与C质量比为1∶3时,PP/EVA/X/C复合材料的综合力学性能较好。与PP/EVA复合材料相比,改性玄武岩纤维(SSiX)和碳纤维(SSiC)增强PP/EVA复合材料的拉伸强度提高了15.73 MPa,弯曲强度提高了30.36 MPa,但冲击强度有所下降。同时,与PP/EVA/X/C复合材料相比,PP/EVA/SSiX/SSiC复合材料的加工性能得到改善,热稳定性也得到了提高。The PP/EVA/X/C composite was prepared with the basalt （X） fiber, carbon fiber （C）, PP and EVA by blending in a double roller mixer. The effect of the proportion of these two kinds of fibers on the mechanical properties of PP/EVA composite was investigated. Meanwhile, the processability, thermal properties and morphology structure of the composite were also analyzed. The results showed that when the proportion of X and C was 1.3, the comprehensive mechanical properties of PP/EVA/X/C composite was better. Compared with the PP/EVA composite, the tensile strength and flexural strength of the modified basalt （SSiX） and carbon （SSiC） fibers reinforced PP/EVA composite increased by 15.73 MPa and 30.36 MPa respectively, but its impact strength declined. In addition, the processability and thermal stability of PP/EVA/SSiX/SSiC composite were improved compared to PP/EVA/X/C composite.
