Bending Properties of Graphene Reinforced Aluminium Matrix Composite Produced by Casting Process

Abstract

The use of graphene as reinforcement for many materials has become popular due to the enhanced properties it has. In this work, different casting methods were aimed to be used in order to produce graphene reinforced aluminum matrix composites. Sand casting, lost foam casting, die casting and squeeze casting methods were used. Graphene was added as layers and also in aluminum foils for incorporation of the reinforcer to the matrix. It was found that squeeze casting was the best method for the production of composite. Bending strength was increased 25-50% for 0.1 wt% graphene added A356 alloy.
