Ceramic component

Abstract

A ceramic component includes a porous fibrous structure that has fibers that are coated with a protective coating. There is a ceramic coating on the protective coating within pores of the porous fibrous structure. The ceramic coating and porous fibrous structure define a residual interconnected porosity. There is a solid glass or glass/ceramic material is within the residual interconnected porosity.

What is claimed is: 
     
         1 . A ceramic component comprising:
 a porous fibrous structure including fibers that are coated with a protective coating;   a ceramic coating on the protective coating within pores of the porous fibrous structure, the ceramic coating and porous fibrous structure defining a residual interconnected porosity; and   a solid glass or glass/ceramic material within the residual interconnected porosity.   
     
     
         2 . The ceramic component as recited in  claim 1 , wherein the protective coating is selected from the group consisting of carbon, boron nitride, boron carbide, silicon nitride, silicon carbide, aluminosilicate and combinations thereof, and the ceramic coating is selected from the group consisting of silicon carbide, aluminum nitride, boron nitride, boron phosphide, silicon nitride, beryllium oxide, diamond and combinations thereof. 
     
     
         3 . The ceramic component as recited in  claim 1 , including a final composition, by volume percentage, of:
 20-70 of the fibers,   up to 5 of the protective coating on the fibers,   5-20 of the coating, and   a remainder of the solid glass or glass/ceramic material and residual void volume, wherein the residual void volume is less than 1 volume percent.   
     
     
         4 . The ceramic component as recited in  claim 3 , wherein the final composition includes:
 30-60 of the fibers,   1-2 of the protective coating on the fibers, and   20-40 of the solid glass or glass/ceramic material.   
     
     
         5 . The ceramic component as recited in  claim 1 , wherein the liquid glass or glass/ceramic material includes a solid ceramic filler. 
     
     
         6 . The method as recited in  claim 5 , wherein the solid ceramic filler includes a silicon-containing material. 
     
     
         7 . The ceramic component as recited in  claim 1 , wherein the porous fibrous structure, ceramic coating and solid glass or glass/ceramic material collectively include less than 1 volume percent of void volume. 
     
     
         8 . The ceramic component as recited in  claim 1 , wherein the solid glass or glass/ceramic material comprises an element selected from a group consisting of boron, barium, magnesium, lithium, aluminum and combinations thereof. 
     
     
         9 . The ceramic component as recited in  claim 7 , wherein the solid glass or glass/ceramic material includes a nucleating agent.
