摘要： The present invention makes use of loose fibrous material (for instance, chopped fibers) as reinforcement matrix material in the manufacture of carbon-carbon composites. In accordance with this invention, a constraint fixture is provided which can be separated from the mold. The constraint fixture has an internal shape corresponding to the shape of a desired preform component, with the internal shape being defined by a bottom plate (2), an annular ejector plate (3, 3'), a inner wall (10), an outer wall (4), and an annular top plate (11, 11'). The constraint fixture is normally made of metal, porous ceramic, or carbon material. The constraint fixture of the mold holds the loose matrix materials (fibers, along with any fillers and/or additives). The mold assembly itself is segmented, so that the constraint- fixture and the loose fill materials in the fixture can be removed and subjected to further processing as a unit. Such further processing may include Chemical Vapor Deposition or resin or pitch infiltration or Resin Transfer Molding. The preform matrix may remain in the constraint fixture through such processing steps as densification and until it is removed therefrom for final machining.
摘要翻译：本发明在制造碳 - 碳复合材料时，使用松散的纤维材料（例如短切纤维）作为增强基体材料。根据本发明，提供了可以与模具分离的约束夹具。约束夹具具有对应于所需预成型件部件的形状的内部形状，其内部形状由底板（2），环形顶出板（3,3'），内壁（10），外壁（4）和环形顶板（11,11'）。约束夹具通常由金属，多孔陶瓷或碳材料制成。模具的约束夹具保持松散的基质材料（纤维，以及任何填料和/或添加剂）。模具组件本身被分段，使得夹具中的约束夹具和松散填充材料可以被去除并且作为一个单元被进一步加工。这种进一步的处理可以包括化学气相沉积或树脂或沥青渗透或树脂转移模塑。预成型体基体可以通过诸如致密化的加工步骤保持在约束夹具中，并且直到其从中移除以进行最终加工。

摘要： A molding process and apparatus suitable for use in molding processes, including rapid prototyping processes and short run production processes. The molding process and apparatus entail the use of a reconfigurable screen tool (10) having a housing (12) defining a manifold cavity (22) and a plurality of substantially parallel pins (16), each having a head (20) protruding from the housing (12) and a shank (18) protruding into the housing (12). The heads (20) of the pins (16) define a screen surface (28) through which air is able to flow, for example, through gaps between adjacent heads (20) or through internal passages (21 ) within the pins (16). The process further includes axially moving the pins (16) to configure the screen surface (28), preventing further axial movement of the pins (16) relative to each other, and then drawing a vacuum within the manifold cavity (22) and creating a vacuum at the screen surface (28).
