Patents by Inventor Harry L. Belvin

Harry L. Belvin 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: 6514370
    Abstract: An apparatus for producing a hybrid boron reinforced polymer matrix composite from precursor tape and a linear array of boron fibers. The boron fibers are applied onto the precursor tapes and the precursor tape processed within a processing component having an impregnation bar assembly. After passing through variable-dimension forming nip-rollers, the precursor tape with the boron fibers becomes a hybrid boron reinforced polymer matrix composite. A driving mechanism is used to pulled the precursor tape through the method and a take-up spool is used to collect the formed hybrid boron reinforced polymer matrix composite.
    Type: Grant

  • Patent number: 6500370
    Abstract: The invention is an apparatus and method for producing a hybrid boron reinforced polymer matrix composition from powder pre-impregnated fiber tow bundles and a linear array of boron fibers. The boron fibers are applied onto the powder pre-impregnated fiber tow bundles and then are processed within a processing component having an impregnation bar assembly. After passing through variable-dimension forming nip-rollers, the powder pre-impregnated fiber tow bundles with the boron fibers become a hybrid boron reinforced polymer matrix composite tape. A driving mechanism pulls the powder pre-impregnated fiber tow bundles with boron fibers through the processing line of the apparatus and a take-up spool collects the formed hybrid boron-fiber reinforced polymer matrix composite tape.

  • Publication number: 20010001408
    Abstract: An apparatus for producing a consolidated, fiber-reinforced composite tape from a plurality of powder pre-impregnated fiber tow bundles having a fiber and a polymeric matrix comprise six (6) major components. Starting at the supply end of the manufacturing line, the components include a pay-out creel, a collimation device, a processing component with an impregnation bar assembly, variable-dimension forming nip-rollers, a self-contained driving mechanism, and a motorized take-up spool. These six components are positioned inoperable relationship to one another.
