PROCESS FOR PRODUCING CYLINDRICAL REINFORCING FIBROUS MOLDING
摘要
A process for producing a cylindrical reinforcing fibrous molding by sealing openings at opposite ends of a porous cylindrical disintegratable mold, immersing the mold into an aqueous solution of a molding material containing reinforcing fibers and an inorganic binder, and depositing the molding material onto the outer peripheral surface of the mold by applying suction within the mold to form a molding blank; pressing the molding blank against the mold to adjust the shape of the molding blank; disintegrating the mold to remove it from the blank; and heating the molding blank to partially bond the reinforcing fibers with the inorganic binder.
