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.

An apparatus and method for securing a plurality of stringers to a mandrel during lay-up is provided, the plurality of stringers and mandrel forming a lay-up surface. The apparatus includes a vacuum source and a first vacuum attachment assembly in communication with said vacuum source to tightly secure the first vacuum attachment assembly down against the lay-up surface. A second vacuum attachment assembly is provided in communication with the vacuum source to force it tightly down against the lay-up. A flexible spacer is in rigid communication with the second vacuum attachment assembly and includes an extended end in communication with the first vacuum attachment assembly such that the flexible spacer presses one of the stringers against the mandrel.

A method and apparatus for a tray, a folding section connected to the tray, and a tape application system. The tray has a channel for receiving an elongate insert for a composite material with a number of layers for a release system. The folding section is capable of folding a number of layers around the elongate insert to cover the elongate insert as the elongate insert is moved through the folding unit. The tape application system is capable of applying a tape to the number of layers for covering the elongate insert to form the release system.

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.
