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.
