  • High-permeability composite prepreg constructions and methods for making the same
    Patent number: 11794377
    Abstract: Methods, apparatuses, and systems for making prepregs are disclosed. A method may include depositing a resin material onto a surface of a fiber bed and forming a number of discrete resin regions thereon. A distance between the resin regions may be measured to provide desired exposed portions of the surface to facilitate permeation of air through the exposed portions of the surface in a direction perpendicular to a plane of the fiber bed during a curing process of the prepreg.
    Type: Grant
    Filed: January 4, 2022
    Date of Patent: October 24, 2023
    Assignee: University of Southern California
    Inventors: Steven Nutt, Lessa Grunenfelder, Timotei Centea, Mark Anders, William Thomas Edwards, Sarah Grace Katz Schechter
