Latest Patents
One of his latest patents is a "Method of fabricating composite structures." This method involves creating a composite structure with at least one skin that is molecularly bonded to a core. The skin is made of reinforcing fibrous material and a thermoplastic matrix, which is thermoformed to match the exterior shape of the composite structure. The core, molded into a complementary shape, is also made of a thermoplastic matrix. The final forming process involves placing the skin and core in a mold and injecting a thermoplastic material under isostatic conditions.
Another significant patent is for a "Dimensionally-stable lightweight core for composite structures." This invention includes a composition for a pressure molded core that consists of a thermoplastic resin, a component to reduce thermal expansion, a lightweight high compressive strength filler, and a blowing agent. The thermoplastic resin may be polyetheretherketone, while the component could be carbon fibers, and the filler may consist of hollow glass microspheres.
