  • Methods and apparatus for making foam composites reinforced with fibers and fiber pre-forms having particles therein
    Patent number: 9387630
    Abstract: According to one aspect, a method of forming foam composites. The method includes providing a plurality of microspheres in contact with a fiber pre-form having a plurality of fibers, inserting at least one penetrating element into the fiber pre-form, and repeatedly moving the at least one penetrating element within the fiber pre-form so as to encourage the plurality of microspheres to disperse within the fiber pre-form. The fiber pre-form with the microspheres dispersed therein is then heated, causing the microspheres to expand and fuse together to form the foam composite.
