    摘要： Tools for manufacturing composite parts and methods for using such tools are disclosed herein. A method in accordance with one aspect of the invention includes manufacturing a fiber-reinforced resin part from a plurality of fibers positioned on a tool having a female mold surface. The mold surface can include a first side region, a second side region, an interior region between the first and second side regions, and transition regions between the first and second side regions and the interior region. The method includes positioning a compaction tool over the mold surface. The compaction tool includes a first pressing device and a second pressing device carrying the first pressing device. The method further includes pressing a first portion of the fibers against the transition regions with the first pressing device without generally compacting the portions of the fibers outboard of the transition regions. After pressing the first portion of the fibers, the method includes pressing a second portion of the fibers against the first and second side regions and shoulder regions of the mold surface outboard of the first and second side regions.

    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 and associated apparatus for forming a composite structural member from a charge are provided. The charge can be disposed on a first die of the apparatus and formed to a desired configuration defined by a recess of the die by inserting a second die or a tool into the recess. In some cases, the first die can include two portions that are adjustable in a transverse direction so that the recess can be opened by the insertion of the second die or tool. The second die or tool can be a substantially rigid member or an inflatable bladder. In either case, the charge can be disposed on the first die, formed, and then further processed on the first die, thereby facilitating indexing of the charge for each operation.

    摘要： The invention disclosed here is a method for forming and curing an intricate structure of criss-crossing composite stringers and frames that are bonded to a skin panel. A structure constructed in accordance with the invention would be well-suited for use as a portion of an aircraft fuselage, a boat hull, or the like. The method is preferably practiced by applying uncured composite stringers to an uncured composite sheet panel. This is followed by placing cured frames crosswise over the stringers. The frames have openings at the locations where they intersect with the stringers which enables the frames to come into direct contact with the skin along most of their length. During the forming and curing process, the stringers are covered with a plurality of cauls, and the entire assembly of skin panel, stringers, frames and cauls is subjected to a vacuum bagging and curing process. The cauls serve to maintain both part shape and to control the flow of resin within the stringers as they are cured. Further, they probably eliminate the need for intermediate protective materials between the vacuum bag and the stringers.

    摘要翻译： 这里公开的发明是一种用于形成和固化结合到皮肤面板的十字交叉复合桁条和框架的复杂结构的方法。 根据本发明构造的结构将非常适合用作飞行器机身，船体等的一部分。 该方法优选通过将未固化的复合桁条施加到未固化的复合板材板来实施。 然后将固化的框架横向放置在桁条上。 这些框架在与桁条相交的位置处具有开口，这使得框架能够沿其大部分长度与皮肤直接接触。 在成型和固化过程中，桁条被多个凹陷覆盖，并且将皮肤面板，桁条，框架和胡须的整个组件进行真空包装和固化过程。 凹槽用于保持两部分形状并且在固化时控制桁条内的树脂的流动。 此外，它们可能消除了对真空袋和桁条之间的中间保护材料的需要。
