Claim 15:
16. A deformable syntactic metal foam composite that is substantially free of non-syntactic porosity; said deformable syntactic metal foam composite includes metal-coated microballoons and a metal matrix material; said metal-coated microballoons have been at least partially secured together by a sintering process; each of said metal-coated microballoons includes a ceramic microballoon and a metal coating; each of said ceramic microballoons for each of said metal-coated microballoons has an average particle size of 5-180 microns; each of said ceramic microballoons constitutes a greater weight percent of said metal-coated microballoon than said coating of metal material on said metal-coated microballoon prior to said sintering together of said metal-coated microballoons; said metal coating on each of said ceramic microballoons is formed by chemical vapor deposition or by immersion in a metal slurry prior to said sintering together of said metal-coated microballoons; at least a portion of said metal matrix material is formed from a metal additive and said metal coating on said metal-coated microballoon; said ceramic microballoons include carbon microballoons, alumino-silicate microballoons, glass microballoons, graphite microballoons, metallic oxide microballoons, metallic carbide microballoons, metallic nitride microballoons, and/or metal silicate microballoons; said metal matrix material includes aluminum, titanium, iron, nickel, copper, cobalt, and/or magnesium; said deformable syntactic metal foam composite includes a solid discontinuous phase comprised of reinforcing material.
