A complex- shaped, three-dimensional fiber reinforced composite structure may be formed by using counteracting pressures applied to a structural lay-up of fiber plies. The fiber plies (104) are arranged on a pressurizable member (106) that may become an integral part of the final product, or may be removed before the product is finalized. The pressurizable member may take the form of a hollow blow molded or rotomolded thermoplastic component or a superplastic formed metallic component having an opening such that the pressurizable member may be vented or pressurized and thus expanded against the fiber plies. In addition, a number of the pressurizable members may be joined in fluid communication, where they may each have different configurations, yet be arranged to form a large, complex- shaped lay-up surface for the fiber plies. The arrangement of the fiber plies onto the pressurizable members may produce integral I-Beam stiffeners, ribs, flanges, and other complex shaped structural components. |
