摘要： A method for fabricating a reinforced matrix composite comprising the step of providing a composite preform having a fibrous structure and applying matrix material onto the preform in locations along the preform. A barrier material is applied to at least a portion of the coated preform to direct the flow of matrix material into the preform. The composite preform is heated to a temperature sufficient to render the matrix material viscous and insufficient to cure the matrix material. The pressure to the interior of the composite preform is reduced, while the pressure to the barrier material is increased. The temperature is maintained to flow the matrix material into the composite preform and to force gases from the fibrous structure. The composite preform is then cured and cooled to form a reinforced matrix composite having a low void content and a substantially uniform matrix distribution.

摘要： A mold tool for forming a reinforced matrix composite part for a gas turbine engine, comprising a body. The body comprises a body surface capable of receiving a first portion of a composite preform. A first endplate and second endplate are attached to the body and include a substantially planar surface disposed perpendicular to the body surface. A first and second set of plates are attached to the first and second endplate adjacent to the body surface and have a geometries that includes a first and second cavity bounded by the first and second plate and first and second endplate. The first and second cavities have a volume sufficient to receive a second portion of a composite preform. The second cavity is in fluid communication with the first cavity, which is in fluid communication with a vacuum source.
