The Development of Equipment and Methods for Studying the Dynamics of the Performance of Light Armor Consisting of Fibrous or a Combination of Fibrous and Metallic Materials.
Abstract
This report deals primarily with the preliminary testing of guided projectiles and attendant problems in the development of equipment to be used for the study of the mechanism by which light personnel armor is able to resist penetration. The results have shown the need for several modifications to the basic equipment, the most important of which include: (a) A projectile guide to maintain accurately the striking attitude of the projectile; and (b) A chronometer capable of discerning residual projectile velocity in the presence of flying armor plate fragments. These two modifications have been completed and operate satisfactorily. Preliminary energy absorption measurements of aluminum plate and fabric-plate sandwiches have resulted in the classification of the types of plate fracture to be expected over a wide range of initial projectile velocities. For a comprehensive study of the problem, it is believed that the effects of low impact velocities must be studied in some detail. Equipment for photographing projectiles in flight and for recording strain gage data has been completed.
