Tests have been conducted over a period of several months at this laboratory on various fabrics which have been suggested as possible components of body armor assemblies. In Tables Xi and XII the various samples are listed in order of figures of merit for resistance ot perforation by cal. .45 bal projectiles and cal. .22 fragment-simulating projectiles, G-2, respectively. These figures of merit are based on the relation between the resistance of a sample to perforation by a given projectile and the resistance of an equivalent weight of Hadfield manganese steel. Since this latter characteristics is reliably known only over the thickness range .040 in. to .050 in, figures of merit have been assigned only to samples whose weight-per-unit-area is equivalent to that of Hadfield steel of that thickness range. Tables XIII and XIV list average figures of merit for the various types of fabrics and afford some basis for relatively evaluating them.
