Abstract: A method for fabricating a grid-stiffened structure from fiber-reinforced composite materials. A skin is applied to a smooth, hard base tool. Ribs comprised of carbon-fiber tows are formed on the skin, and shallow cavities are formed between the ribs and the skin. An expansion block is placed in each of the cavities, and is held in place by an elastomeric contact adhesive having adhesive properties that are substantially diminished when the adhesive is heated to an elevated curing temperature. The assembly is then autoclave cured. After cooling, the formed structure is separated from the base tool and the expansion blocks are removed from the cavities. A grid-stiffened sandwich structure is formed by applying an outer skin over the ribs and expansion blocks, before curing the assembly. After cooling, the outer skin is removed to allow extraction of the blocks, and subsequently bonded to the ribs.

Abstract translation: 一种从纤维增强复合材料制造网格加强结构的方法。 皮肤应用于光滑，坚硬的基础工具。 在皮肤上形成由碳纤维丝束组成的肋，并且在肋和皮肤之间形成浅的腔。 膨胀块放置在每个空腔中，并且通过具有粘合性质的弹性体接触粘合剂保持在适当位置，当粘合剂被加热到升高的固化温度时，粘合剂性质基本上减小。 然后将组件高压釜固化。 在冷却之后，将形成的结构与基础工具分离，将膨胀块从空腔中移出。 在固化组件之前，通过在外肋和膨胀块上施加外皮来形成网格加强的夹层结构。 冷却后，除去外皮以允许块的提取，随后粘合到肋上。

Abstract: 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.
