PROCESS FOR THE PREPARATION OF FIBRE REINFORCED METAL MATRIX COMPOSITES AND NOVEL PREFORMS THEREFOR

摘要

A process for the preparation of a fibre reinforced metal matrix composite comprising fibres embedded in a metal in which the process comprises forming a body with a layer of aligned fibres between at least two layers of metal foil and densifying said layers wherein the layer of aligned fibres comprises metal particles interposed between individual fibres, the metal particles being compatible with the metal foil. A preform for a fibre reinforced metal matrix composite is also claimed which comprises a resin and a layer of aligned fibres, the layer having metal particles interposed between adjacent fibres, and the layer and particles being bonded together with the resin.
