  • Publication number: 20100319841
    Abstract: A fabrication method of forming a thermoplastic composite laminate material with tailored and varying thickness in a continuous process. This process utilizes automated equipment or hand lay-up to collate parts or components into a multi-layer stack. Each stack contains all plies, including ply build-up areas, tacked in the proper location to maintain orientation and location. The consolidation tooling contains all necessary part features and is coordinated to the customized multiple ply stacks to form a single integrated thermoplastic composite laminate potentially having areas of differing thickness from these multiple ply stacks.

  • Publication number: 20100225016
    Abstract: A device changes the shape of a die used to compression mold a part. The device includes a sleeve placed between the die and a charge to be molded. The sleeve has an inner face generally conforming to a face of the die, and a outer face for molding a part.

  • Publication number: 20090078362
    Abstract: A process for forming curved thermoplastic composite material. According to an illustrative embodiment, the process includes providing a length of straight thermoplastic material; pre-forming the length of straight thermoplastic material into a selected cross-sectional configuration; pressing the length of the straight thermoplastic material; and imparting a curved shape to the length of straight thermoplastic material by providing a curved section and passing the length of straight thermoplastic material through the curved section of a process assembly.

  • Publication number: 20080185756
    Abstract: Thermoplastic laminates are fabricated in a continuous compression molding production line. A lay-up of laminate plies is placed in a recess on a carrying tool, and the tool is moved through successive forming operations on the line, including preforming and consolidation operations. The tool is separated from the fully formed part at the end of the line and may be reused. Use of the carrying tool reduces material scrap.

  • Publication number: 20070175573
    Abstract: Thermoplastic composite parts having integrated metal fittings are manufactured using a continuous compression molding process. Automated equipment or hand lay-up are used to collate composite material plies and metal fittings into a multi-layer stack. Each stack contains all plies, including ply build-up areas, tacked in the proper location to maintain orientation and location. Multiple lay-ups may be cut from each stack. The lay-ups are placed in tooling containing part features and are continuously fed through a performing station where the lay-ups are preformed into the approximate shape of the finished part. Following pre-forming, the tooling is moved incrementally through a consolidation station where a compression press presses successive sections of the tooling to form a single integrated thermoplastic composite laminate part having integrated metal fittings, which may include areas of differing thickness.
