Method of forming composite articles from CVD gas streams and solid particles or fibers

A method of forming a composite article comprising:

• forming a mixture of a solid phase material and a reactant gas, said reactant gas being thermally activatable to produce chemical vapor deposition (CVD) vapors and other reaction products;
• providing a substrate compatible with said reactant, gas, said CVD vapors, said other reaction products, and said solid phase material;
• heating said substrate to a temperature sufficient to activate said reactant gas upon contact;
• contacting said heated substrate with said mixture so that said reactant gas reacts to produce said CVD vapors;
• and
• codepositing said solid phase material and material from said CVD vapors onto said substrate to form a composite article consisting essentially of (i) a solid matrix formed by chemical vapor deposition of said material from said CVD vapors and (ii) said solid phase material dispersed within said solid matrix.
