    Abstract: A resin transfer molding (RTM) process is disclosed for rapidly filling a fibrous preform and/or a rigid, porous body with high viscosity resin or pitch. The process is suitable for impregnated multiple porous bodies stacked in a single mold. The process uses a fibrous preform or rigid porous body which is placed into a mold matching the desired part geometry. A resin is injected into the mold at temperature and pressure. After cooling, the infiltrated component is removed from the mold. The mold is constructed from two halves fitted to form at least one mold cavity. A gate fitted with a nozzle is set into one of the mold halves, and a valve admits resin or pitch into the gate area. Venting or vacuum can be applied to the mold. The mold is held in a hydraulic press and an extruder, optionally fitted with an accumulator, supplies molten resin or pitch to the mold.

    Abstract: Resin or pitch is melted in a melt blender apparatus (11) and then loaded, into a heated jacketed holding tank (12). A pair of feed lines (14, 16) receives resin from the holding tank (12) and feeds an upper gear pump (15) and lower gear pump (17). A mixing enhancement such as a static mixer (18, 19) is located in each of the feed lines (14, 16) between the gear pumps (15, 17) and the resin delivery ends (25, 26) of the feed lines. The resin-melt feed lines may be equipped with pressure indicators (27, 28, 32, 34) and pressure relief valves (23, 24). The resin-melt feed lines may also be equipped with pump accumulators (31, 33). Resin melt pressure created by the gear pumps (15, 17) forces a piston inside the accumulator back to the desired position. The accumulators (31, 33) can also be used to maintain constant pressure in the feed stock. Resin can be recycled from the accumulators (31, 33) into the melt blender (11).

    Abstract: Molding apparatus for rapid transfer of molten resin or pitch in an infiltration molding process. The apparatus includes e.g. an extruder ( 4 ) for melting and conveying a resin or pitch and a mold ( 10 ) arranged so that resin or pitch is conveyed to a mold insert cavity ( 19 ) within the mold. The mold insert contains an internal protrusion such as a locating ring ( 25 ) for positioning a porous body ( 1, 18 ) within the mold insert cavity in a position that brings about unidirectional flow of the molten resin or pitch through the porous body. Also, rapid resin or pitch infiltration molding process that includes injecting a high melting point, high viscosity, molten resin or pitch into the mold to effect a unidirectional impregnation of a heated preform via a pressure gradient in the mold.
