1. A method of forming a surface-treated, fabric-reinforced prepreg composite comprising:
infiltrating an inorganic fabric with a first slurry mixture to form an infiltrated fabric, wherein the first slurry mixture comprises an oxide component and a liquid media;
infiltrating an inorganic paper with a second slurry mixture to form an infiltrated paper, wherein the second slurry mixture comprises an oxide component and a liquid media; and
applying the infiltrated paper to a surface of the infiltrated fabric to form a surface-treated, fabric-reinforced prepreg composite,
wherein the inorganic fabric has a thickness of from about 5 mm to about 75 mm prior to being infiltrated with the first slurry mixture,
wherein the inorganic paper has a thickness of from about 0.1 mm to about 4.99 mm prior to being infiltrated with the second slurry mixture, and
wherein the inorganic paper includes non-woven, randomly oriented inorganic fibers that provide structural reinforcement in surface-treated prepreg composites and layups thereof where these inorganic fibers may take the form of chopped fibers, continuous fibers, filaments, tows, bundles, sheets, plies, or any combination thereof.
