发明名称 Method and system for fabricating parts from composite materials
摘要 A method for fabricating a composite part (42) from a plurality of composite layers (14) is provided. The method includes laying-up the composite layers (26) one upon another to form a collection of layers in a configuration and debulking the configuration of layers (26) by applying pressure sufficient to reduce the thickness of the layers to within approximately twenty percent (20%) of the part's final thickness. The debulked layers (28) may then be stored, generally at room temperature. To later form the part, the debulked layers (28) are heated to a temperature above their glass transition temperature and formed into the part's final shape. Heat may then be continuously applied to the layers while holding them in the part's final shape with sufficient force to achieve and maintain the part's thickness and density and until the heating causes the layers to become sufficiently cured so that the part's shape, thickness, and density are maintained.
