摘要: 以环氧树脂(EP)、双马来酰亚胺(BMI)、4,4’-二氨基二苯砜(DDS)和短切碳纤维(SCF)等为主要原料制备了EP/BMI/DDS/SCF复合材料,并研究了SCF添加量对复合材料力学性能和热性能的影响。结果表明,当SCF添加量为0.25 %(质量分数,下同)时,EP/BMI/DDS/SCF复合材料的力学性能提高最大,其拉伸强度、弯曲强度、弯曲模量和缺口冲击强度比未添加SCF时的EP/BMI/DDS复合材料分别提高了48.52 %、32.15 %、25.77 %以及150.91 %;此外,SCF的加入有助于提高复合材料的热性能。

Abstract: Epoxy composites were prepared with E-51,BMI,DDS, and short carbon fiber (SCF) and the effect of the content of SCF on the mechanical and thermal properties of the composites was studied. It was found that when the carbon fiber content was 0.25 %, the mechanical properties of the composites were optimal and the tensile strength, flexural strength, flexural modulus, and notch impact toughness were increased by 48.52, 32.15, 25.77, and 150.91 % based on than that of EP/BMI/DDS composite without carbon fiber. In addition, carbon fiber improved the thermal properties of the composites.
