The Mechanical Properties of Metal-Void Composites

Abstract

Work under this contract is intended to conduct a theoretical feasibility study of the strength, toughness and vibrational damping properties of composite materials consisting of a metallic matrix with a high volume fraction (to 30%) of small (0.1 - 10 microns) pressurized voids. The premise of the approach is that a theoretical study, using both analytical and computer methods, offers a cost-effective means of assessing the probable properties of such composites and their projected utility in aerospace structures.
