  • Composite material with thermoplastic toughened novolac-based epoxy resin matrix
    Patent number: 10465052
    Abstract: Pre-impregnated composite material (prepreg) that can be cured/molded to form aerospace composite parts. The prepreg includes carbon reinforcing fibers and an uncured resin matrix. The resin matrix includes an epoxy component that is a combination of a hydrocarbon epoxy novolac resin and a trifunctional epoxy resin and optionally a tetrafunctional epoxy resin. The resin matrix includes polyethersulfone as a toughening agent and a thermoplastic particle component.
    Type: Grant
    Filed: September 19, 2018
    Date of Patent: November 5, 2019
    Assignee: HEXCEL CORPORATION
    Inventors: Yan Zhu, Gordon Emmerson, Yen-Seine Wang, Maureen Boyle, Jessica Leandro
