Abstract

A metal matrix composite comprises randomly-oriented inorganic oxide fibres of density below 3 g/ml embedded in a metal matrix material such as a light metal, for example aluminium or magnesium or an alloy thereof. In a particular embodiment the fibres are of density 1.8 to 2.5 g/ml and preferably are of mean diameter from 2 to 10 microns. The composite can be made by liquid infiltration of a fibre preform comprising the fibres bound together with an inorganic or an organic binder or by extrusion of a mixture of the fibres and a powdered metal matrix material.
