Abstract:
1. A monolithic structural panel comprising: a skin, and mutually orthogonal frame and stinger members attached to the skin and forming a plurality of junctions therebetween, wherein each of the frame members, stringer members and skin is formed of a fiber-reinforced composite material, and wherein the junctions between the mutually orthogonal frame and stringer members include cross-plied laminae of fiber-reinforced composite material and opposed mirror image pairs of preformed modular junction elements, wherein the preformed modular junction elements include mutually orthogonal component webs, each mutually orthogonal component web of one preformed modular junction element being abutted against a respective mutually orthogonal component web of another preformed modular junction element to thereby form mutually orthogonal component frame and stringer webs establishing respective parts of the frame and stringer members.
