Abstract: Economical metal reinforced organic fabrics (hybrid fabrics) were developed that had one order of magnitude (10X) higher cut and slash resistance than their un-reinforced commercial counterparts. These fabrics are coated with polymeric resins to form what are in effect single layer fabric-reinforced organic matrix composites. The force required to cut through these hybrid compositions was determined to be similar to that needed to defeat premium para-aramid and ultra-high molecular weight polyethylene fabric controls. The cut resistance of the hybrids was compared to that of standard industrial nylon fabrics and to those of Kevlar, a high performance aromatic polyamide. Heavy, medium and light basis weight hybrid fabrics representative of target end-uses in transportation, architecture, marine and living space protection were made and tested. Their design, processing, performance and economics are presented. The attractiveness of hybrid production in repurposed 2-D weaving equipment, their potential for product differentiation, and the mitigation of commercialization risks are discussed.
