摘要： A composite stiffener is fabricated using preforms of laminated, unidirectional composite tape. The stiffener includes a void that is reinforced by a filler wrapped with a structural adhesive. The surfaces of the preforms surrounding the void include a layer of composite fabric which is bonded to the filler by the adhesive, thereby increasing the toughness of stiffeners around the void and improving pull-off strength of the stiffener.

摘要： A machine and a method for forming composite materials are provided. The machine includes a frame and at least one forming beam attached to the frame, the at least one beam being arranged to align with a mandrel. The forming beam is pivotally segmented into at least two segments to conform to the shape of the mandrel, or alternately is bendable to conform to the shape of the mandrel. The mandrel is receivable within the frame in alignment with the forming beam. An apparatus is also provided to position a composite charge over the mandrel, and to position the mandrel within the frame. A further apparatus is provided to transport the mandrel, and to urge the mandrel toward the forming beam, forming a composite charge.

摘要： A method for forming composite materials is presented, including providing a composite charge wider than a first surface of a mandrel, and positioning the composite charge across the first surface of the mandrel. The portion of the composite charge overhanging the first surface of the mandrel is supported and urged against the mandrel while supporting the unbent portion of the composite charge substantially parallel to the first surface of the mandrel. The invention also provides a system, using a compression mold of forming bladders and heater plates, to form a composite charge over a mandrel, while supporting the unbent portions of the composite charge during forming substantially parallel to the upper surface of the mandrel. The present invention minimizes the shear zone where plies in the composite laminate charge slide past one another during the forming process reducing or eliminating out-of-plane fiber buckling.
摘要翻译： 提出了一种用于形成复合材料的方法，包括提供比心轴的第一表面更宽的复合电荷，以及将复合电荷定位在心轴的第一表面上。 承载突出于心轴的第一表面的复合材料电荷的部分被支撑并推压在心轴上，同时支撑基本平行于心轴的第一表面的复合电荷的未吸收部分。 本发明还提供了一种系统，其使用形成气囊和加热器板的压缩模，以在心轴上形成复合电荷，同时在基本上平行于心轴的上表面的成形过程中支撑复合电荷的未吸收部分。 本发明使复合层压材料中的层片在成形过程中相互滑过的剪切带最小化，从而减少或消除了平面外的纤维弯曲。

摘要： A method of manufacturing curved composite structural elements can include fabricating a web ply in a flat curve over a removable substrate and laying up the ply on a curved web surface of a manufacturing tool. The method also can include laying up a diagonal ply with fibers oriented at +/−45° from the centerline of the web surface. The method further can include cutting a unidirectional composite tape into segments and laying up the tape segments to form a cross ply with a fiber orientation normal to the centerline of the web surface. One or both edges of the diagonal and cross plies may be folded over one or two sides of the manufacturing tool to form one or two flange surfaces. Additionally, a cap ply can be laid up on one or both flange surfaces using composite tape. The structural element layup can then be inspected and any excess composite material can be trimmed away.
