Abstract
A method and system of preparing a releasable underlying support for use in preparing a composite laminate is presented where a base tool is a covered with a conformable thin sheet on the tooling surface of a base tool, where the thin sheet is configured with one high tack surface side and an opposite side having a non-tack surface in contact with the tooling surface. The non-tack surface side will allow release of laid up pre-cure composite lamina that can then be cured on a separate curing tool. The thin sheet is positioned over the base tool and a vacuum source and sealed around the perimeter edge of the base tool. Drawing a vacuum causes the non-tack surface side of the film to be drawn downward into contact with the tooling surface. Plies of pre-cure lamina can then be added to the base tool covering and adhering to the high tack surface side.
