Abstract
A curved composite material body is consolidated to a complexly curved shape by placing rigid tooling on the concave-facing side of the body, and a pressure membrane on the other (convex-facing) side of the body. In another region of the body where the sign of the curvature of the body changes so that the other side becomes the concave-facing side, the rigid tooling is placed on that side, against the concave-facing side, and the pressure membrane is contacted to the convex-facing side. The rigid tooling thus crosses over from one side to the other through various regions of the body, providing a precise consolidation to meet the structural and dimensional specifications. Consolidation is achieved by applying pressure to the body of composite material through the pressure membranes.
