RAPID DENSIFICATION OF POROUS BODIES PREFORMS WITH HIGH VISCOSITY RESINS OR PITCHES USING A RESIN TRANSFER MOLDING PROCESS

摘要

The fiber preform and / or rigidity, rapidly filling the high viscosity resin or pitch transfer molding resin in the porous body (RTM, resin transfer molding) is disclosed. ; This method is suitable for the impregnated porous multi-layered body in a single mold. ; This method utilizes a fibrous preform or a rigid porous body disposed in the mold matching the desired part geometry. ; The resin injected into the mold under the pressure and temperature. ; After cooling, the number of the penetrating component from the mold. ; Fulfill at least one mold cavity of the mold consists of two half. ; And a gate for the nozzle is set to one of its two halves, valve accepts the resin or pitch into the gate region. ; The template can be applied to the vent or vacuum. ; The mold is held by fluid pressure, and is optionally equipped with an accumulator extruder supplies the molten resin or pitch into the mold.
