Abstract
A preform charge is formed by forming an assemblage of preforms, wherein preforms in the assemblage are bonded to a neighboring preform such that the preform charge effectively becomes a single unit. The preform charge can then be added to a mold to fabricate a part via compression molding.
Claims28
A method for forming a fiber composite part, the method comprising:
- providing at least a first preform charge having only a single, continuous length of prepreg, and having a shape that substantially conforms to at least a first portion of a mold cavity into which the at least preform charge is to be placed;
- placing the at least first preform charge in the mold cavity;
- closing the mold cavity;
- and
- applying heat and pressure to the at least first preform charge to form the fiber composite part.
