Patents by Inventor Bert D. Mannhalter

Bert D. Mannhalter 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: 11951690
    Abstract: A method for processing massive fiber bundles includes massive fiber-bundle formation and massive materials handling, wherein plural small-diameter bundles are unified, while more or less preserving their legacy cross-sectional form. It also includes bending, such as to create non-linear preforms, and preform-charge fabrication. Embodiments of the invention operate to help preserve a desired fiber alignment throughout a part fabricated from relatively large-diameter fiber bundles.

  • Patent number: 11951696
    Abstract: A cosmetic part is formed via compression molding in a single molding operation with no post processing by forming an assemblage of feed constituents, wherein the assemblage includes plural fiber-bundle-based preforms and one or more resin-only constituents, the latter configured and positioned as appropriate to create resin-rich cosmetic layers where desired on the part.

  • Publication number: 20230311372
    Abstract: An improved compression-molding process utilizes a unique assemblage of feed constituents, arranged, and aligned in a particular manner. The assemblage includes fiber-bundle preforms having a filamentous form with a typically circular or oval cross section, and having many thousands of relatively long, co-aligned, resin-impregnated fibers. The fiber-bundle preforms are formed to have an application-appropriate length and optionally shape. The assemblage further includes very-short-fiber constituents have a filamentous form and consisting of very short, typically non-aligned, resin-impregnated fibers. Although consisting of very short fibers, the very-short-fiber constituent may nevertheless be similar in length and cross section to the FB preforms to facilitate handling, registration with a mold cavity, and the like.

  • Publication number: 20220355513
    Abstract: A method for cleaning or treating a mold includes form a cleaning charge or a release-agent charge, placing the charge in a mold cavity and applying heat and pressure to the charge, thereby conforming the charge to the mold cavity and forming a mock part, and then ejecting and discarding the mock part. During processing of the cleaning charge, contaminants adhering to the walls of the mold cavity from previous molding runs are incorporated into the mock part. During processing of the release-agent charge, release agent is transferred from the charge to the surface of the mold cavity.

  • Patent number: 11306195
    Abstract: The invention relates to compositions comprising composite materials comprised of discontinuous fibers and one or more polymers and/or oligomers. The invention relates to methods of making the same. The composite materials can be in the form of compositions, composite sheets, laminates, pellets, and/or shaped composite products.

  • Publication number: 20220009176
    Abstract: A method for improving the impact resistance of a fiber-composite part includes positioning fibers within an expected impact region of the part, wherein at least a portion of most of the positioned fibers is oriented to be within about 45 degrees of parallel to an impact vector of an impact that occurs at the impact region. At least some of the fibers in the impact region should have relatively high impact resistance, such as glass fiber or aramid fiber, and the matrix in the impact region should have relatively high impact resistance.
