摘要： A fiber-composite material (7) is comprised of a yarn aggregate (6) in which yarn (2A, 2B) including at least a bundle (3) of carbon fiber and a carbon component other than carbon fiber is three-dimensionally combined and integrally formed without separation from each other; and a matrix made of Si-SiC-based materials (4A, 4B, 5A, 5B) filled between the yarn (2A, 2B) adjacent to each other within the yarn aggregate (6). A method of preparing fiber-composite material is comprised of the steps of: producing bundles (3) of carbon fiber by impregnating a component of powdery carbon into the bundles (3) of carbon fiber, which eventually forms a matrix shape; forming a plastic coat around the bundles (3) of carbon fiber to obtain an intermediate material; molding the intermediate material to obtain a molded product by making the intermediate material into a yarn-shape and laminating a predetermined amount of the material, or burning the molded product to obtain a burned product; holding the molded product or the burned product and Si, at 1100 to 1400°C in an atmosphere of inert gas; and heating the molded product or the burned product and Si to a temperature from 1450 to 2500°C, to thereby impregnate Si-SiC-based material into the inside of pores of the molded product or the burned product. A light and strong composite material is provided, which has excellent shock resistance, corrosion resistance in a strong oxidation and corrosion environments, creep resistance, spalling resistance, wear resistance, a low friction coefficient and a self-restorative ability by which a defect is healed.

The friction-clutch system of this invention has a friction disk unit comprising a central hub and friction disks,
wherein the friction disks have a first friction surface facing a flywheel and a second friction surface facing a pressure plate,
wherein the flywheel has a third friction surface facing the first friction surface,
wherein the pressure plate has a fourth friction surface facing the second friction surface of the friction disks,
wherein at least one friction surface of the first to fourth friction surfaces is constituted of different materials, i.e., comprised of a combination of a carbon/graphite material and a metal/ceramics material,
wherein the carbon/graphite material forms a friction surface made from a carbon/graphite material, and a metal/ceramics material forms a friction surface made from a metal/ceramics material,
wherein the ratio of [the area of the friction surface made from the metal/ceramics material]/[the area of the friction surface made from the metal/ceramics material + the area of the friction surface made from the carbon/graphite material] ranges from 0.05∼0.65, and
wherein pressure between the first and the third friction surface and between the second and the fourth friction surface is 10∼250 N/cm 2 while the power is being transmitted.

摘要： A fibrous composite material composed of a yarn assembly (6) comprising yarns (2A, 2B) containing at least carbon fiber bundles (3) and carbonaceous components other than carbon fibers, the yarns (2A, 2B) being three-dimensionally combined and integrated so as not to cause mutual separation, and a matrix comprising Si-SiC-base materials (4A, 4B, 5A, 5B) filled between adjacent yarns in the yarn assembly. The composite material is produced by forming a plastic film around each carbon fiber bundle containing powdery carbon, forming the same into yarns followed by molding, and impregnating silicon into the open cells of the product of molding at high temperature. This material is excellent in impact resistance, can be used in a strongly oxidizing corrosive environment, has a light weight and a high strength, and is endowed with a self-restorability for being healed of defects.
