摘要： A fiber reinforced composite structure includes multiple plies of pre-impregnated fiber reinforced material. Consecutive plies are layered such that the fibers of one ply are at 90 degrees relative to the fibers of a proximate ply, and such that the fibers of each ply are oriented at positive or negative 45 degrees with respect to a reference plane of the fiber reinforced composite structure. In a method for fabricating a fiber reinforced composite structure, pre-impregnated fiber reinforced composite plies are layered into a tool layup. Each ply is cut on the bias at either plus 45 degrees or minus 45 degrees. The bias angles of the layered plies alternate one relative to the next. The layered plies are cured after layering.

摘要： A method for making a fuselage section comprises the steps of assembling a support system. The support system comprises fiber reinforced composite material and includes at least three frames and six stringers. The support system is partially cured such that the support system attains about eighty percent of its fully cured strength. A skin comprising fiber reinforced composite material is globally positioned such that an inner surface of the skin corresponds to an outer surface of the support system. The skin and the support system are fully cured together. The support system is assembled on a skeleton assembly tool having a bonding surface corresponding to an inner surface of the skin.
