Abstract
A composite and a process for forming it are provided, said process comprising providing a substrate bearing crystalline and preferably single crystal filaments as growths on the substrate and forming a solid matrix encompassing the filaments. The composites are useful for aircraft, boat and auto skins and structural members.
Claims21
A process for forming a novel composite comprising providing a substrate bearing crystalline filaments as growths on the substrate and forming a solid matrix encompassing the filaments, wherein the filaments are substantially uni-directional in a direction other than perpendicular to the substrate.
The process of claim I wherein substrate is removed following the step of forming.
A continuous process for forming a novel composite comprising continuously feeding a suitable substrate to a filament growing station and forming crystalline filaments on said substrate, passing the resultant filament laden substrate to a matrix dispenser station and treating said filament laden substrate with a liquid, normally molten, matrix material, allowing the resultant coated product to solidify and continuously recovering the solid product wherein the filaments are substantially uni-directional in a direction other than perpendicular to the substrate.
A process of improving the properties of a composite comprising a substrate bearing filaments as growths on the substrate, said process comprising aligning a plurality of said filaments in substantially the same direction.
