REINFORCED COMPOSITE MATERIAL AND MANUFACTURE THEREOF

摘要

PURPOSE:To improve the wettability of an inorg. reinforcing material for a matrix and maintain the high temp. strength of the material constant by coating the material surface with a specified semi-inorg. cpd.; thermally decomposing the cpd.; and combining the resulting material with the matrix. CONSTITUTION:The surface of an inorg. reinforcing material such as glass, ceramics or metal fiber is coated with a semi-inorg. cpd. such as polycarbosiloxane convertible into ceramics based on amorphous, beta-type or alpha-type SiC or mixed phase SiC by heating at 400-2000 deg.C in a nonoxidizing atmosphere. The coated material is heated to 400-2000 deg.C to thermally decompose the cpd. The resulting material is then combined with a matrix such as metal, ceramics or plastics by a suitable method to manufacture a composite reinforcing material. It has high strength at room temp. and superior high temp. properties and is suitably used as a building material, a material for corrosion resistant apparatus, etc. in various uses.
