The report presents the experimental results and related discussions of a study on the factors controlling ballistic penetration of textile materials. In addition to a description of the experimental apparatus, the report presents data on ballistic and Instron penetration tests for a variety of polymeric films, natural and polymeric fibers in bonded, spun-bonded, woven, needled, and knitted textile fabrics. SEM studies on impacted fabrics are included. Results indicate energy absorption capability depends on the ability of the fabric structure to propagate large strains as well as its rupture or penetration strength. The former is dependent on the degree of locking within the fabric for a given material the latter was dependent on the tensile strength and modulus of the fabric with the greater energy absorption capability residing with the low modulus, flexible materials.
