A ballistic laboratory was designed and built to accommodate the impact of . Kevlar® woven fabric of varying ply levels, while manipulating the geometrical shape, weight, and impact velocity of the projectile. A chronograph system was used to measure the striking and residual velocities of the missile. Empirical relations were determined between the experimental data and the quantity 1/√L, where L is the ogive length of the projectile. This quantity was found to be useful in characterizing projectile geometrical effects on the impact performance of woven fabric systems. The effects of projectile shape on the number of fabric plies, velocity loss data, and thus V50 values are characterized by the empirical relations.

A review of plasma treatments of textiles is presented. The utility of plasma technology in processing textiles and the corresponding changes brought about in textile properties are discussed. The initiative, funded by the National Textile Center, and its progress to date is presented. This program features the use of enhanced high density plasmas for depositing films, removing surface matter, and altering surface properties.
