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.
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.

This chemical heat pump includes two reaction sections R1 and R2 containing a thermal storage medium; an evaporation-condensation section D containing water or steam; connection sections H18 to H21 connecting the reaction sections R1 and R2 to the evaporation-condensation section D; and two fluid channels individually disposed so as to correspond to the reaction sections. A "first state in which the reaction section R1 is set to a heat-storing state and the reaction section R2 is set to a heat-release state" and a "second state in which the reaction section R1 is set to a heat-release state and the reaction section R2 is set to a heat-storing state" are alternately applied every time after a first period elapses. For each reaction section, in the heat-release state, a fluid is caused to flow from a first side to a second side of the corresponding fluid channel over a first period; and, in the heat-storing state, a fluid is caused to flow from the second side to the first side of the corresponding fluid channel over a second period.

The "heat storage material storage container" comprises "a main body having a longitudinal direction and including a plurality of flow channels therein, the flow channels extending parallel to each other in the longitudinal direction and separated from each other by porous walls" and "a heat storage material contained in only one or some of the plurality of flow channels." The plurality of flow channels include "a plurality of first flow channels each having an open end on a first side in the longitudinal direction and a closed end on a second side in the longitudinal direction" and "a plurality of second flow channels each having open ends on both the first side and the second side in the longitudinal direction." The heat storage material is contained in only the first flow channels.

A kiln tool plate 1 for firing a ceramic material used during the firing of an article to be fired, wherein at least uneven conformations 3 are imparted to a front surface side A on which the article to be fired is mounted and a back surface side B, and opening areas 7 are formed. In the ceramic material firing kiln tool plate 1, the decrease of heat capacity and the reduction of costs can be achieved, a contact area with the article to be fired is decreased to improve outgassing, and the atmosphere can be made uniform to uniformly manufacture the fired article. Above all, the kiln tool plate for firing the ceramic material has excellent thermal shock resistance, creep resistance, high strength at high temperature and oxidation resistance, and enables weight saving.
