摘要：
A composition for a pressure molded core of a composite structure, including a thermal plastic resin. The composition also includes a component to reduce the coefficient of thermal expansion, a lightweight high compressive strength filler, and a blowing agent. The thermoplastic resin may be polyetheretherketone, the component may be carbon fibers, and the filler may be hollow glass microspheres.
