摘　　要：采用超声波分散法制备多壁碳纳米管增强树脂基复合材料,研究了多壁碳纳米管质量分数对树脂基复合材料力学性能的影响规律。结果表明:多壁碳纳米管的加入可有效地改善树脂基复合材料的韧性和强度,当多壁碳纳米管质量分数为0.7%时,树脂基复合材料的力学性能最佳。加入多壁碳纳米管后,树脂基复合材料的玻璃化转变温度降低,且相容性良好。Multi-Walled Carbon Nano-Tubes/EPoxy resin(MWCNTs/EP) matrix composite materials are prepared by the ultrasonic dispersed method,and the effect law of MWCNTs mass fraction on the mechanical property of the epoxy resin matrix composite materials is investigated.The results of mechanical property show that the toughness and strength of the MWCNTs/EP composite materials could be greatly improved.When the mass fraction of MWCNTs is 0.7%,the mechanical property of the MWCNTs/EP composite materials is the best.The glass temperature of MWCNTs/EP composite material is decreased by adding MWCNTs,and its compatibility is good.
