Document Type and Number:
Japanese Patent JP3483035
Kind Code:
B2
Abstract:
This invention relates to a process comprising the steps of:a) providing a fiber preform comprising a non-oxide ceramic fiber with at least one coating, the coating comprising a coating element selected from the group consisting of carbon, nitrogen, aluminum and titanium, and the fiber having a degradation temperature of between 1400° C. and 1450° C.,b) impregnating the preform with a slurry comprising silicon carbide particles and between 0.1 wt % and 3 wt % added carbonc) providing a cover mix comprising:i) an alloy comprising a metallic infiltrant and the coating element, andii) a resin,d) placing the cover mix on at least a portion of the surface of the porous silicon carbide body,e) heating the cover mix to a temperature between 1410° C. and 1450° C. to melt the alloy, andf) infiltrating the fiber preform with the melted alloy for a time period of between 15 minutes and 240 minutes, to produce a ceramic fiber reinforced ceramic composite.
