The Law Enforcement Assistance Administration LEAA is sponsoring a program to develop an inconspicuous, lightweight body armor that will provide protection from standard handgun threats. A high-speed projectile that impacts but does not penetrate flexible armor material transmits large amounts of energy to the underlying tissues. The goal of this study was to determine the hazards resulting from impacts with the .38-caliber, 158-grain bullet, at approximately 800 feet per second. The missiles impacted 7 plies of Kevlar 29 4002 denier directly over the myocardium. Extensive cardiac monitoring of 23 anesthetized Angora goats was performed. The study that small myocardial contusions, damage to the valvular structures, and great vessel injury can be produced.
