A CERAMIC FIBER PREFORM AND ITS FABRICATION METHOD FOR METAL MATRIX COMPOSITE

摘要

A pre-forming material composed of 40-50wt% alumina, 36-40wt% silica, 13-16wt% Zirconia and less than 54wt% regular foreign material are manufactured. Further, the pre-forming material is injected into a liquid metal or an aluminium alloy on which apply pressure and maintain until it is solidified. After solidification provides heat treatment and obtains a ceramic fiber reinforcement metal complex material.
