Abstract
A method for preparing a part using a rigid tool surface having a shape. The method includes applying a breather sheet comprising gas-permeable material over the rigid tool surface. A vacuum bag is applied over the breather sheet, and a vacuum pressure is applied underneath the vacuum bag to conform the breather sheet and the vacuum bag to the shape of the rigid tool surface. A resin pre-impregnated ply is applied over the vacuum bag, and the part is positioned over the ply.

A method of preparing a part using a rigid tool surface having a shape, the method comprising:
- applying a vacuum bag over the rigid tool surface;
- applying vacuum pressure to the vacuum bag to conform the vacuum bag to the shape of the rigid tool surface;
- applying a resin pre-impregnated ply over the vacuum bag;
- and
- applying the part over the ply.
A system for preparing a part using a rigid tool surface having a shape, the system comprising:
- a vacuum bag positioned over the rigid tool surface and being under vacuum pressure conforming the vacuum bag to the shape of the rigid tool surface;
- and
- a resin pre-impregnated ply positioned adjacent the vacuum bag opposite the rigid tool surface,
- wherein the part is positioned adjacent the ply opposite the vacuum bag.
