International Journal of Mechanical and Industrial Engineering

This article depicts the processing and mechanical characterization of a new class of multi-phase composites consisting of polyester resin reinforced with glass fiber and filled with alumina particulates. Four different composite samples are prepared with 0, 5, 10 and 15wt.% of Al2O3(alumina). The mechanical properties of these composites are evaluated. It is found that Al2O3 modifies the tensile, flexural and the inter-laminar shear strength of the glass-polyester composites. The hardness and density of the composites are also greatly influenced by the content of these fillers.
