The Production-scale Squeeze Casting of Devitroceramic Fiber Reinforced Aluminum and its Mechanical Properties

Abstract

This study was carried out to apply fiber reinforced metal to general-purpose machine parts, resulting in a successful large-scale production of machine parts made of devitroceramic fiber reinforced aluminum alloy by the use of the conventional die casting facility and in clarification of necessary production conditions. Mechanical tests were then performed for fiber reinforced metals themselves and hybrid composites, and it was made clear that their tensile strength at elevated temperatures, wear resistance and damping characteristics were better than those of matrix metals, suggesting the applicability of the composite materials to special-duty machine parts.
