A6061/B4C MMCs fabrication, experimental investigation and prediction of properties

Abstract

The growing demand for light composite materials is the new trend in engineering solicitations. The objective is to fabricate light weight composite material through less expensive method. In this work, nine different composites have been fabricated with A6061 as base matrix and reinforced with 3%/6%/9%wt%B4C having particle sizes of 30µm, 40µm and 60µm respectively. The investigation of the actual density and hardness of the fabricated composite is the major task. The densities of the fabricated composites were investigated with Two-way Analysis of Variance(ANOVA). Also the densities of the composites were predicted with Taguchi, regression and Poisson method. From all of these fabricated composites 60µm size, 9% wt B4C particle reinforced A6061/B4C composite shows lighter density and this value were nearest to Poisson predicted value.
