43 MOLD FOR PAD MOLDING OF POWDER EP86906437.8 1986-10-21 EP0243502A1 1987-11-04 EGUCHI, Tooru Kabushiki Kaisha Kouransha nai; KURITA, Sumihiko 91-26, Oaza-Miyano

A mold for use in the pad molding of powders of inorganic, organic or metallic materials. As a basic material that constitutes the mold, the invention uses a single material which exhibits changes of states, such as from liquid to gas or solid, softening -- hardening and low viscosity -- high viscosity depending on temperature, or a mixture of this material with other powder or a material impregnated with this material. A mold cavity is formed at a temperature at which this material is hardened or highly viscous and, after molding, a pad molding product is released from the mold at a temperature at which this material is liquid, softened or lowly viscous, or while this material is dissipated from the mold. This operation can prevent the pad molding product from being damaged during mold release operation.

PURPOSE:To provide a compsn. excellent in moldability and giving a fiber reinforced ceramic molded body having high strength and a low shrinkage by blending silicon nitride-based ceramic powder with inorg. fibers and an org. binder. CONSTITUTION:Silicon nitride-based ceramic powder is blended with inorg. fibers and an org. binder to obtain the objective compsn. for producing a fiber reinforced ceramic molded body. Aluminum oxide fibers and/or silicon nitride fibers are suitable for use as the inorg. fibers. An emulsion of polyurethane having hydrophilic groups is suitable for use as the org. binder. The compsn. is molded by slip casting or other method to produce the objective fiber reinforced ceramic molded body. Even a molded body for a ceramic member of a complex shape is produced without causing damage or cracking.
