Abstract:
1. A laminate composite structure comprising: a solid laminate; a composite sandwich structure, integrally connected to the solid laminate; said solid laminate comprising a first plurality of plies of material layered at interspersed orientations within a stacking sequence; said composite sandwich structure comprising a top face sheet and a bottom face sheet with a core material disposed between, wherein the top face sheet and the bottom face sheet of the sandwich structure are adjacent to a first side and a third side of the core material and comprised of extended outer plies of the first plurality of plies of material; a second plurality of plies of material disposed in the laminate composite where the inner plies of the solid laminate terminate, wherein a first end of the second plurality of plies of material extend from the point of termination of the inner plies of the solid laminate for a specified distance that does not exceed the extension of the top face sheet and the bottom face sheet of the composite sandwich structure, said core material having a second side adjacent a second end of the second plurality of plies of material, and wherein the plurality of inner plies of the solid laminate terminate sequentially, beginning with the innermost ply first and continuing outward toward the top and bottom face sheets, and wherein each ply of the second plurality of plies of material begins where an inner ply of the solid laminate terminates and each ply of the second plurality of plies of material terminates in the same location, creating a wedge of material plies inserted into the laminate composite such that the total number of plies in the laminate composite remains the same from the solid laminate up to the core material; and a plurality of pins in the solid laminate, at locations in the geometry of the solid laminate where the solid laminate forms a bend.
