Composite layer forming system

摘要

A method and apparatus for forming a stack of composite layers into a desired shape is present. The stack of composite layers may be positioned on a tool and a number of compressible supports such that the stack of composite layers may be substantially flat on the tool and the stack of composite layers may be substantially flat on the number of compressible supports. A flexible sheet may be placed on top of the stack of composite layers. A vacuum load may be applied on the stack of composite layers on the tool and the number of compressible supports using the flexible sheet such that consolidation of the stack of composite layers occurs to form a desired shape on the tool and the number of compressible supports compress during forming of the desired shape.

1. An apparatus comprising:
a platform configured to receive a tool; a number of compressible supports configured to be placed on the platform in a number of locations such that a stack of composite layers positioned on the tool and the number of compressible supports is substantially flat on the tool and the stack of composite layers is substantially flat on the number of compressible supports; and a flexible sheet configured to be placed on top of the stack of composite layers such that a vacuum drawn on the flexible sheet results in the flexible sheet applying a vacuum load on the stack of composite layers on the tool and the number of compressible supports such that the stack of composite layers forms a desired shape on the tool and the number of compressible supports compress during forming of the desired shape.
