摘要: 利用溶液共混法制备不同质量分数(0,3.2%,11.2%)BN、AlN纳米颗粒改性IR3环氧树脂(EN/EP,AlN/EP)复合材料,研究了纳米颗粒含量对树脂黏度和复合材料力学性能的影响。结果表明:添加BN和AlN纳米颗粒使树脂黏度增加了5%~10%;BN/EP和AlN/EP复合材料的拉伸强度较纯环氧树脂提高了10%~25%,随BN、AlN含量的增加而增大;AlN/EP复合材料的剪切强度提高了40%~60%,随AlN含量的增加而增大,但BN/EP复合材料的剪切强度随BN含量增加几乎不变;当纳米颗粒质量分数为11.2%时,环氧树脂黏度适中,复合材料的力学性能最好。Abstract: Different mass fractions (0,3.2%,11.2%) of BN on AlN modified IR3 epoxy resin (BN/EP,AlN/EP) composites were prepared by solution blending method. The effects of nanoparticle content on the resin viscosity and the tensile and shear properties of the composites were studied. The results show that adding BN and AlN nanoparticles improved the resin viscosity by 5%-10%. The tensile strength of BN/EP and AlN/EP composites increased by 10%-25% comparing with that of the pure resin, and the tensile strength increased with the increase of BN and AlN content. The shear strength of the AlN/EP composite increased by 40%-60% comparing with that of the pure resin, and the shear strength increased with the increase of AlN content, but the shear strength of BN/EP composite was almost unchanged with the increase of BN content. When the mass fraction of nanoparticles was 11.2%, the epoxy resin had moderate viscosity and the mechanical properties of the composites were the best.
