摘要： A contoured composite structure is fabricated by laying up a composite charge that includes at least one ply formed by uni-directional fiber pre-preg ply segments having substantially constant widths. The ply segments are placed in side-by-side, overlapping relationship with their longitudinal centerlines aligned in a polar orientation related to the contour of the structure. The charge is formed into the shape of the structure and cured.

摘要： A method is provided for forming a composite part contoured along its length and having at least one leg. The method includes forming a stack of fiber reinforced, pre-preg plies by laying down individual segments of unidirectional fibers in each ply. Each of the segments is placed in a preselected orientation related to the contour of the part. The leg is formed by bending a portion of the stack over a tool.

摘要： A method and apparatus for curing composite materials that emit large volumes of volatiles during processing. The apparatus includes tooling having a rigid forming surface contoured to the shape of the formed composite part. A plurality of passages extend from the forming surface through the tooling. The passages are in fluid contact with an exhaust port. A composite workpiece is laid up and placed adjacent the forming surface. The apparatus includes a heater that heats the composite workpiece to temperatures at which volatiles are emitted. An evacuation system draws the volatiles away from the composite workpiece through the passages in the tooling and out of the exhaust port. One embodiment of tooling according to the invention is used to form a sine wave spar. The tooling includes upper and lower tool inserts upon which U-shaped composite channels are formed. The upper and lower tools are placed adjacent to each other to form the web of the spar. Cap strips are placed on either side of the joined U-shaped channels. Side rail tools are then placed adjacent the cap strips. A breather cloth is placed over the tools and the entire assembly is placed within a vacuum bag. The assembly is then placed within an autoclave and connected to the vacuum exhaust of the autoclave. During processing, volatiles are drawn away from the composite workpiece through the passages in the tooling using the vacuum exhaust.

The systems and methods may be configured to create a pre-form that may be utilized to form a radius filler and/or create a radius filler from the pre-form. Creating the pre-form may include extending a plurality of lengths of composite tape from a composite tape source and receiving the plurality of lengths of composite tape in a pre-form forming structure, converging and/or otherwise combining the plurality of lengths of composite tape within the pre-form forming structure to produce the pre-form, and/or withdrawing the pre-form from the pre-form forming structure. Creating the radius filler from the pre-form may include receiving the pre-form in a radius filler forming structure and producing the radius filler from the radius filler forming structure.

摘要： A stiffened skin panel of an aircraft that includes an aircraft skin panel of composite material and a composite stringer consolidated with the aircraft skin panel. The stringer has a pair of stringer sides, each extending from a stringer top to a stringer leg. The stringer sides may each extend through a wide radius, smooth continuous curve to a stringer leg. The wide radius, smooth continuous curve may be proximate the base of the stringer side in a region where the stringer side transitions to the stringer leg.
