PROCESS FOR PRODUCING CYLINDRICAL REINFORCING FIBROUS MOLDING

摘要

A process for producing a cylindrical reinforcing fibrous molding which comprises the steps of: sealing openings at opposite ends of a cylindrical disintegratable mold having a porosity, immersing the mold into an aqueous solution of a molding material containing a reinforcing fiber and an inorganic binder, and depositing the molding material onto an outer peripheral surface of the mold by applying an suction within the mold to form a molding blank; pressing the molding blank against the mold to adjust the shape of the molding blank; heating and drying the molding blank; disintegrating the mold for removal; and firing the molding blank to partially bond the reinforcing fiber with the inorganic binder.
