  • Impact-resistant molded composites and methods therefor
    Patent number: 12017420
    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.

  • Method for processing massive fiber-composite preforms
    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.

  • Method for compression molding cosmetic composite parts
    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.
