    摘要： A porous substrate of a fuel cell electrode assembly is formed by producing a fibrous carbon precursor web by means of a conventional wet paper-making process. The precursor web is then dried and saturated with a wet resinous binder which will carbonize when heated. Substantially the entirety of all of the carbon fibers in the web are thus coated with the binder, and substantially all of the inter-fiber junctures in the web will also be coated with the binder. The saturated web is then dried, and heat treated to convert the binder to a glassy carbon which exhibits superior resistance to corrosion.

    摘要： The present invention relates to high temperature composite materials formed from nano-sized powders suitable for use in the manufacture of jet engine components. The composite materials consist essentially of a matrix formed from a powdered material having a particle size in the range of from about 1 to about 100 nanometers and a plurality of reinforcing fibers embedded within the matrix and comprising from about 20% to about 40% by volume of the composite material. The method of manufacturing the composite materials broadly comprises the steps of mixing the powdered material with the reinforcing fibers and consolidating the mixture to form the composite material.

    摘要： An uncooled turbine outer air is comprised of a combination of monolithic ceramics with high temperature capability and oxidation and creep resistance, and a fiber reinforced ceramic composite with high fracture toughness. In a preferred embodiment of the invention, a fiber reinforced ceramic composite of silicon carbide and aluminum borosilicate is infiltrated by chemically vapor deposited silicon carbide. The infiltration process is continued until the composite develops a monolithic layer of silicon carbide. An additional layer is deposited on the monolithic ceramic to provide additional thermal protection.
