Mechanical Properties of Glass Fiber Reinforced Epoxy Composites Filled with Al 2O3 Particles

An experimental study has been carried out to investigate the mechanical properties of glass-fiber reinforced epoxy composite filled with different proportions of Al 2 O 3 particles. As a comparison, the mechanical properties of unfilled glass-fiber reinforced epoxy composite were also evaluated under identical test conditions. The results showed that while ultimate tensile strength and shear strength of the composites decreased with increasing Al 2 O 3 particles content, flexural strength increased with the Al 2 O 3 particles content of up to 10% beyond which it decreased. Compared with the flexural properties of the unfilled glass-fiber reinforced epoxy composite, with the addition of 10 wt% of Al 2 O 3 particle in the matrix, flexural strength, and flexural modulus were increased by 33 and 78%, respectively.
