Abstract:

A method and an apparatus are presented. The method locally compensates for cure related deformations in a composite skin by laying up a composite material on a compensation surface of a slip sheet designed to form a modified outer mold line different from a designed shape, wherein the slip sheet is held against a forming surface of a layup tool, wherein the forming surface is designed to form an outer mold line of the designed shape.
