Inflatable pressure intensifier
This invention describes novel design and construction method for inflatable, pressure intensifier equipment that can be used for processing composites structures. The equipment can be used as a manufacturing and processing platform wherever low pressure and high temperature inputs are required in an enclosed volume.
METHOD OF REINFORCING A SEAM AND A PRODUCT WITH A REINFORCED SEAM IN ACCORDANCE WITH THE METHOD
A method of reinforcing a seam on a body involves folding a seam allowance into a series of accordion folds to form a series of parallel reinforcement layers. The parallel reinforcement layers are of similar size and form a ridge. A ridge cap of flexible material is placed over the ridge. The ridge cap provides at least one further parallel reinforcement layer. The method involves securing the ridge cap and parallel reinforcement layers together with rows of stitching, with the stitching extending through all of the parallel reinforcement layers.
Thermoformed cascades for jet engine thrust reversers
A cascade for a jet engine thrust reverser is fabricated by co-consolidating pre-consolidated thermoplastic strongbacks and vanes. The strongbacks are reinforced with continuous fibers, and the vanes are reinforced with discontinuous fibers.
Controlling application of forces to different portions of object surface using bladder
Provided are methods and apparatuses for processing objects by applying different forces and/or pressure levels to different portions of surfaces of these objects. An apparatus may include a flexible wall and a contact member. In some embodiments, the flexible wall forms a bladder such that the contact member is disposed inside the bladder. During operation, the flexible wall may be pressed against an object using a pressure differential across the wall (e.g., by pressurizing the bladder). This creates a first force acting on a first portion of the object surface. Furthermore, the contact member may be forced against the flexible wall and apply a second force to a second portion of the object surface through the wall. The second portion of the object surface may be a subset of the first portion or an entirely different portion.

Composite slat can assembly and methods of making same
A slat can assembly with a slat can body includes at least one full ply of a composite fiber sheet material and a plurality of elongated, unidirectional fiber ply strips that are arranged into the shape of the slat can body. At least some of the unidirectional fiber ply strips are laid over the full ply. And, the full ply and the elongated, unidirectional fiber ply strips cooperate to provide a contoured shape defined by a cellular core member.
