Abstract

The epoxy matrix toughened by nano-Al2O3 was prepared by mechanical mixing method. The mechanical properties of epoxy matrix with different nano-Al2O3 content were researched. The fracture toughness of the epoxy matrix was studied by compact tension test method. The glass-fiber reinforced composites were fabricated using the toughened epoxy matrix and the mechanical properties of the composites were investigated. The results indicate that the improved fracture toughness of epoxy matrix and the enhanced bonding between fibers and resin matrix can be attributed to the nanoparticles. Therefore, the interlaminar shear strength of the composites is improved obviously, while the other mechanical properties increase faintly.
