Abstract
A laminated chemical and biological resistant, flexible material is disclosed, along with a process of fabricating the material. A base fabric of woven construction forms a support layer for the material. A thermoplastic base coat is applied and laminated to at least one side of the base fabric. A top camouflage coat is applied and laminated to the base coat, the top coat comprising a thermosetting chemical and biological resistant material. The base fabric may be open-weave and the base coat is adhered thereto by physically filling the interstices of the open-weave. The base fabric may be closed-weave and the base coat includes a bonding agent for adhering to the base fabric. In the preferred embodiment, the base fabric is a polyester or nylon material, the base coat is a polyvinyl chloride material and the top coat is a coating compound from a group consisting of aliphatic polyurethanes, polyvinylidene chloride, butyl rubber, and the like. Alternately, a chemical and biological resistant film barrier may be laminated in the material, the film comprising a compound from a group consisting of nylon, polyethylene terephthalate, polyacrlonitrile, polyvinylidene chloride, and the like.
