    摘要: Fiber-reinforced, ceramic composite articles are manufactured by contacting inorganic reinforcing fibers with liquid dispersions containing powders of the ceramic matrix materials and an organic binder. The organic binder is a water-soluble polymer. The fibers coated with the ceramic powders are contacted with a cross-linking agent which reacts with binder to form a gel.

    摘要: An improved, laminated, ophthalmic lens structure, and method of producing the structure. The structure comprises two adjacent layers of dissimilar, organic plastic materials, either or both of which contain matter that tends to migrate. The improvement comprises a barrier layer that is intermediate the adjacent organic plastic layers; that is impermeable to migrating matter; and that is composed of a polyolefin polymeric material modified by the presence of acid or anhydride functional groups.

    摘要: Fiber-reinforced ceramic matrix composite articles are fabricated by combining inorganic reinforcing fibers with dispersions of powdered ceramic matrix materials in organic vehicles which are thermoplastic solids. The dispersions are solid at room temperature, and are melted and combined with the fibers as heated liquid dispersions. Following application to the fibers, the thermoplastic dispersions are solidified by simple cooling; no solvent removal or drying step is required.
