Ceramic Matrix Composites as Armor Materials. Part 2

Abstract

Specimens of nichrome wire mesh reinforced, titania doped alumina and spinel have been fabricated by pressure calcintering and ballistically tested. The samples were right circular cylinders, 4 in. diameter x 1/4-3/4 in. thick. Photographs of ballistically tested samples, illustrating the types of fracture incurred, are given. A six months feasibility study of these and other composites is reviewed. Microstructural examination shows no degradation of the wire reinforcement or the matrix materials during fabrication. Sapphire fibers and whiskers did not significantly enhance the properties of the spinel and alumina matrices; the sapphire whiskers were dissolved in the matrix materials during fabrication.
