Abstract : This patent application discloses an invention that relates generally to metal matrix composites (MMC) materials, and more particularly to polymer-reinforced metal matrix composites wherein polymer filaments are formed during processing of the MMC. MMC's incorporating a less-dense reinforcing non-metal have been developed for use in low-density applications such as for aircraft components. Other improved mechanical properties are toughness, specific strength, and specific modulus of metals such as aluminum and titanium. These can be enhanced by reinforcing them with boron, carbon, or silicon carbide filaments. It is the general object of the present invention to provide a method of producing a polymer-reinforced metal matrix composite. More particularly, it is an object to provide a simple and relatively inexpensive method of producing a polymer-reinforced metal matrix composite and to provide a method of producing a polymer-reinforced metal matrix composite wherein polymer filaments or films are formed during processing. Another object is to provide a polymer-reinforced metal matrix composite which can be subsequently processed by a variety of methods. The invention is to provide an aluminum matrix composite material with reduced density, increased specific strength, enhanced damage tolerance, and increased mechanical damping capability compared to the corresponding properties of the aluminum material alone.
