DEVICE AND METHOD OF TRANSFER MOLDING OF RESIN OR PITCH Russian patent published in 2006 - IPC B29C70/48 

FIELD: modified method of fast compacting of high-temperature materials, carbon-to-carbon composites (C-C composites) and porous briquettes by high-viscosity resin or pitch.

SUBSTANCE: proposed device for transfer molding of resin or pitch includes unit for melting and transporting resin or pitch, mold with projection for forming pressure gradient and making resin or pitch move over inner area of mold in way of its external area; device is also provided with unit for clamping the mold in the course of delivery of resin or pitch to it; this unit is located near mold. Method of fast transfer molding of resin or pitch includes placing porous briquette in mold; briquette is heated to temperature above melting point of resin or pitch; mold is provided with clamping unit for retaining its configuration; then molten resin or pitch at high melting point and high viscosity is delivered to mold for homogeneous impregnation of briquette due to pressure gradient in mold and conditions for cooling the resin below its melting point are created and briquette thus impregnated is withdrawn from mold.

EFFECT: fast filling of fibrous briquette and/or solid porous body with high-viscosity resin or pitch at high temperature.
