  • Patent number: 6406580
    Abstract: A method for manufacturing composite parts includes positioning a plurality of composite layers on an application surface formed by a plurality of tooling members and filler members on a mandrel. A part formation aid is disposed on the composite layers above each tooling member. The filler members are then removed, and the composite layers slit over the recesses. The mandrel, the tooling members, the composite layers, and the part formation aids are placed in a vacuum bag. As the bag is evacuated, each part formation aid forces the side edge of the composite layers formed by the slit around the respective tooling member, thereby forming a composite part with a desired shape, thickness, and density. In an alternate embodiment, a flanged composite panel is formed around a rectangular mandrel after positioning composite layers on an outer surface of the mandrel and an outer surface of a filler member disposed on one end of the mandrel.

  • Patent number: 6171535
    Abstract: The process for fabricating an orthotic joint of the present invention involves creating a casting mold of the anatomical joint for which the brace is being fitted. Then layers of nylon and cross-link carbon composite grade and the PVA bag are placed over the mold as is done in typical laminating processees for such braces. Then, a series of reinforcing strips of nylon and composite are attached to the layup in the same location where the sidebars would normally be located. The bottom layer which is typically a layer of nylon stockinette is the longest of the layers and the nylon strips are alternated with the composite strips with each successive strip being shorter than the strip immediately below it. A dummy disk is then provided at the joint. A second set of strips is then positioned where the upper sidebar would be located. Additional laminating substrate materials of nylon and cross-link carbon composite braid and a PVA bag are then placed over the structure.
