摘　　要：采用碳纤维(CF)制备CF增强聚碳酸酯/丙烯腈-丁二烯-苯乙烯共聚物(PC/ABS)复合材料,研究CF对PC/ABS复合材料的力学性能和热学性能的影响,以获得CF的最佳掺量。力学性能分析表明,随着CF质量分数的增加,CF增强PC/ABS复合材料的拉伸强度和弯曲强度不断提高,冲击强度先增大后减小。热学性能分析表明,随着CF质量分数的不断增加,CF增强PC/ABS复合材料的热变形温度不断提高,熔体流动速率(MFR)先增大后减小。CF的质量分数为15%时,CF增强PC/ABS复合材料的综合力学性能和热学性能最优,与未加CF的材料相比,拉伸强度、弯曲强度和冲击强度分别提高了134.7%、133.3%和69.6%,热变形温度提高了39℃,MFR提高了27.8%。The article uses carbon fiber(CF)to prepare CF reinforced polycarbonate/acrylonitrile-butadiene-styrene copolymer(PC/ABS)composites,and studies the influence of CF on the mechanical and thermal properties of PC/ABS composites,in order to obtain the optimal content of CF.Mechanical property analysis shows that as CF increases,the tensile strength and flexural strength of CF reinforced PC/ABS composites continuously increases,while the impact strength first increases and then decreases.Thermal property analysis shows that with the continuous addition of CF,the heat deflection temperature of CF reinforced PC/ABS composites continues to increase,and the melt flow rate(MFR)first increases and then decreases.When the CF mass frction is 15%,the comprehensive mechanical and thermal properties of CF reinforced PC/ABS composites are optimal.Compared with the material without CF,the tensile strength,flexural strength,and impact strength are increased by 134.7%,133.3%,and 69.6%,respectively,the heat deflection temperature is increased by 39℃,and the MFR is increased by 27.8%.
