摘要： An uncured, thermoset resin sheet is reinforced with oriented fibers and is slit to define a desired length for the fibers. A series of the sheets are cut and stacked to form integrated layers of the composite material for a structural panel. The panel has two outer layers that sandwich two shorter layers on each end, and syntactic or foamed resin layer in between. Each of the composite layers is formed from the same materials and by the same process, but may vary in the directional orientation of their fibers. The uncured panel is assembled into a flexible, substantially flat configuration is heated and formed to the contours of a tool having a undulated surface geometry. The panel is further heated to cure the combined composite and syntactic resins into a series of undulations that permeate each of its layers. In one embodiment, the undulations are in a smooth, sine wave-like pattern that allow the panel to maintain a planar configuration. Although the fibers themselves do not stretch, the short lengths of the fibers enable stretching of the material in the fiber direction so that deformation of the composite is possible in all directions. The panel is stiffened both by spacing its outer layers apart with the syntactic layer, and by its undulated surface.

摘要： According to one embodiment of the invention, a method of constructing a composite structure includes positioning a plurality of forming elements on a skin panel formed from a composite material in a predetermined configuration, disposing a stiffening panel formed from an uncured composite material outwardly from the forming elements to create a plurality of contact regions between the skin panel and the stiffening panel, and curing the skin panel and the stiffening panel to bond the skin panel and the stiffening panel together at the contact regions.

摘要： A preformed component or "preform" (11) for a structural member has a planar base with two longitudinal legs (15, 17) extending in parallel from the base (13). A channel (19) is defied between the legs (15, 17) for insertion of a plat panel (31) that forms the web of the structural member. The preform (11) is a composite material having continuous filaments of woven or braided fiber (21). The preform (11) is impregnated with a thermoset resin that bonds the web of the flange of the structural member. The perform (11) provides excellent structural support even if the web of the flange are formed from dissimilar materials such as metallic and composite. The resin is structurally reinforced with oriented fibers in such a manner as to provide coupling strength between the joined members.
