The objective of this program was to investigate the potential of the space-wound structural concept to provide a ballistic tolerant structure to the high explosive projectile. The spacewound structural concept, developed by Fiber Science, Inc., is an open weave wet filament wound composite structural concept which has the potential for venting the blast pressure from the high explosive projectile while at the same time providing a multiplicity of redundant load paths. Twelve 24-inch diameter cylindrical specimens were designed and fabricated by Fiber Science, Inc., and were subsequently ballistically tested at the Applied Technology Laboratory, Fort Eustis, Virginia. Three materials (Kevlar, Fiberglass, and Graphite), two fiber coverage ratios, and the use of an external fiberglass aerodynamic skin surface were assessed. Based on the results of these tests, four with a fiberglass cloth skin, two with 25 % and two with 50 % fiber coverage ratio, were selected for final design evaluation. The final speciment for final design evaluation. The final speciments were 16-inch diameter cylinders with a four-bolt ring/frame attachment fitting at each end to facilitate structural testing.
