HIGH TEMPERATURE PRESSURE MOLDING FURNACE MEMBER CONSISTING OF CARBON FIBER REINFORCED CARBON COMPOSITE MATERIAL AND ITS PRODUCTION

摘要

PROBLEM TO BE SOLVED: To obtain a cylindrical furnace member without splinter which is prevented from peeling of laminated layer during production and has durable strength in repeating operation for long period for time, by using a carbon composite material having a reinforced layer comprising carbon fiber sheet of at least 3 layers structure which is laminated by winding in a peripheral direction. SOLUTION: Reinforced composite layers are obtained by laminating alternately winding a carbon fiber sheet which consist of a reinforced layer obtained by winding and laminating a carbon fiber sheet comprising internal and outer layers of short spinning fibers and an intermediate layer of short spinning fiber, and a carbon fiber sheet contg. continuous fiber or continuous fiber bundle. The short spinning fiber sheet is particularly pref. a textile. Both of warp and weft in the sheet generally consist of spinning fibers of carbon fibers. Orientation of the textile is preferably arranged so that peripheral direction is coincided with the warp or the weft. In the case that the textile consists of the continuous fiber bundle and the short spinning fiber, the textile in which the short spinning fiber is exposed to the surface is pref.
