Squeeze Casting을 이용한 금속 복합재료 제조공정 개발

Abstract

Optimum manufacturing process in a vacuum assisted squeeze casting is investigated for continuous SiC and Boron fiber reinforced aluminum matrix composites based on the previous result of single fiber reinforced metal matrix composite(MMC)s. Squeeze casted specimens under different processing conditions are measured their interracial bonding strengths and tensile strengths to verify the applicability of the obtained process range of single fiber reinforced MMCs. It is found that manufactured 16% volume fraction SiC fiber reinforced aluminum MMCs under the optimum range show two times higher tensile strengths than the aluminum matrix itself and can keep their strengths up to 400℃.
