ABSTRACT:
Metal foams are impregnated with a phthalonitrile prepolymer. The metal f/polymer composite formed upon curing has excellent acoustic damping, structural properties, oxidative stability, and flame resistance. Foams of various metals, such as aluminum, titanium, nickel, copper, iron, zinc, lead, silver, gold, platinum, tantalum, and alloys based on these metals may be used.
