A liquid metal infiltration process has been developed to fabricate a low density, porous metal matrix composite (PMMC). The composite consists of an aluminum alloy matrix containing uniform, hollow, thin-shell spheres, termed aerospheres, composed of alumina. The PMMC is lightweight, inexpensive to fabricate, and has potential application when weight savings is of paramount importance. The densities of an Al-Al2O3 composite range from 1.3-1.8 gms/cc and can be controlled by the physical properties of the aerosphere and/or the volume fraction of spheres in the composite. The emphasis of this presentation will be on the compressive failure mechanism of the low density PMMC utilizing the additive properties of the aerosphere and aluminum phase.
