Rock/Elastomer Composites as Impact Resistant Materials

Abstract

Composites cast from polymers, rock aggregates and sand have been examined to determine their resistance to penetration by 7.62mm diameter high velocity projectiles. The effects of using different polymer and rock aggregate types have been investigated, and the resultant composites optimized in terms of cost effectiveness and penetration resistance. Optimization was carried out using response surface theory and variables considered were mix proportions, rock aggregate particle size and polymer hardness. Penetration tests were carried out on optimized composites to determine the thickness required for a given confidence level of projectile containment. (Author)
