Patents by Inventor Charles Richard PREBIL

Charles Richard PREBIL has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10118350
    Abstract: Continuous compression molding process and apparatus for fabricating thermoplastic composite parts from pre-formed thermoplastic composite laminates with tooling dies have a staggered bevel feature at an entry side of the tooling dies. Staggering the length of the bevel feature in each section between bends in a surface contour along the width of the incoming edge of the tooling dies prevents excess material from being trapped and forming wrinkles in the finished thermoplastic part. The length of the taper in each section along the width of the tooling dies is aligned with a pulsed advancement distance of the pre-formed part.
    Type: Grant

  • Patent number: 10029398
    Abstract: A method and apparatus for forming a stiffened thermoplastic panel is presented. The method may comprise placing a number of forming tools within a number of concave areas of a thermoplastic preform. The method may also place the thermoplastic preform with the number of forming tools within the number of concave areas on a thermoplastic lay-up to form a workpiece. The method may also position the workpiece within a tool. The tool may have a number of die liners configured to generate heat in response to a magnetic field. The method may also consolidate the workpiece to form the stiffened thermoplastic panel. Consolidating may comprise applying a magnetic field to the number of die liners to heat the workpiece to a consolidation temperature.

  • Patent number: 9545778
    Abstract: A mechanical pressure application system for applying a tailored pressure distribution to a plurality of structural components is provided. Each structural component has a first surface, and each first surface is configured to interface with the first surface of another of the structural components at a contact area. A base and at least one tooling block are configured to removably couple to the structural components. Each at least one tooling block includes a first surface configured to be positioned proximate at least one of the plurality of structural components. A second surface of each tooling block is configured to receive at least one forcing member. At least one biasing mechanism is configured to apply a predetermined load to the at least one forcing member, such that a force is transmitted from the at least one forcing member through the tooling block to a corresponding portion of the contact area.
