摘要： 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.

摘要翻译： 公开了一种用于快速填充具有高粘度树脂或沥青的纤维预型体和/或刚性多孔体的树脂传递模塑（RTM）方法。 该方法适用于堆叠在单个模具中的多个多孔体。 该方法使用纤维预成型体或刚性多孔体，其被放置在与期望的部件几何形状相匹配的模具中。 在温度和压力下将树脂注入模具中。 冷却后，将渗透的组分从模具中取出。 模具由安装成形成至少一个模腔的两个半部构成。 装有喷嘴的门被设置在其中一个半模中，并且阀门允许树脂或沥青进入浇口区域。 通风或真空可以应用于模具。 将模具保持在液压机中并且可选地装有蓄能器的挤出机将熔融树脂或沥青供应到模具。
