Resistance of Various Samples of 'Fiberglas' to Perforation by Fragment-Simulating Projectiles
Abstract
As part of a program of development of improved body armor components, requested by the Office, Chief of Ordnance, and in response to a specific directive from this office, several types of Fiberglas, furnished by the Owens-Corning Fiberglas Corporation and varying in weave, weight and texture, have been tested ballistically at this arsenal. The resistance of these samples to perforation by cal. .45 (steel-jacketed) ball projectiles and by cal. .22 fragment-simulating projectiles seems to reflect the characteristics of the yarn and the closeness of their texture, since those showing greatest resistance were closely woven and made of fine-fibred, multi-stranded, high-twist yarn while the affording lowest resistance were less closely woven and made of yarn with coarser fibres and a lower number of strands, Theresistance of the best sample to perforation by cal. .45 ball projectiles compares favorably with that of an equivalent weight of 17 1/2 ounce nylon duck, which has exhibited the greatest resistance of any fabric tested here, but underthe impact of the cal. . 22 fragment-simulating projectile, G-2, it was considerably inferior. However, the resistance of Hadfield manganese steel of equal weight is much greater than either of these fabrics.
