Abstract
Resin infused composite parts are fabricated using a caul sheet having perforations therein for optimizing the flow of resin through the parts. The method allows for a simplified tooling and consumable arrangement for complex parts while achieving a smooth, aerodynamic caul-side or bag-side finish. The component may be placed in direct contact with a tool, and the caul sheet may be placed in direct contact with the component thereby eliminating the necessity for consumables between these items.
