A method for applying multiple polymeric coatings onto a fibrous substrate. More particularly, a method for applying multiple polymeric coatings onto fibrous substrates without regard to chemical or physical incompatibilities of the polymeric coating materials. A first polymeric material is applied
A method for applying multiple polymeric coatings onto a fibrous substrate. More particularly, a method for applying multiple polymeric coatings onto fibrous substrates without regard to chemical or physical incompatibilities of the polymeric coating materials. A first polymeric material is applied onto at least one fibrous substrate, and a second polymeric material is applied onto a support. The fibrous substrate and support are joined, contacting the first polymeric material with the second polymeric material, followed by separating the support from the fibrous substrate, such that at least a portion of the second polymeric material remains on the first polymeric material on the fibrous substrate.

1. A method of forming a fibrous composite, which comprises: a) providing a fibrous substrate comprising a woven fabric, the woven fabric having a first liquid polymeric material an a surface thereof;b) providing a support, the support having a second liquid polymeric material on a surface thereof;
1. A method of forming a fibrous composite, which comprises: a) providing a fibrous substrate comprising a woven fabric, the woven fabric having a first liquid polymeric material an a surface thereof;b) providing a support, the support having a second liquid polymeric material on a surface thereof; wherein said first polymeric material and said second polymeric material comprise different polymers;c) thereafter, joining the woven fabric and the support by contacting the first liquid polymeric material with the second liquid polymeric material such that the first liquid polymeric material and second liquid polymeric material are contacted with each other while each polymeric material is wet; and thend) separating the support from the woven fabric, such that at least a portion of the second polymeric material remains on the first polymeric material on the woven fabric. 2. The method of claim 1 wherein step a) comprises applying the first liquid polymeric material onto the woven fabric, and wherein step b) comprises the step of applying the second liquid polymeric material onto the support. 3. The method of claim 1 wherein the first liquid polymeric material and the second liquid polymeric material are dried after step c) but prior to step d). 4. The method of claim 1 wherein the first liquid polymeric material and the second liquid polymeric material are dried after step d). 5. The method of claim 1 wherein said woven fabric comprises one or more fibers, each fiber having a tenacity of about 7 g/denier or more and a tensile modulus of about 150 g/denier or more. 6. The method of claim 1 wherein said woven fabric comprises one or more polyolefin fibers, aramid fibers, polybenzazole fibers, polyvinyl alcohol fibers, polyimide fibers, polyethylene terephthalate fibers, polyethylene naphthalate fibers, polyacrylonitrile fibers, liquid crystal copolyester fibers, rigid rod fibers comprising pyridobisimidazole-2,6-diyl (2,5-dihydroxy-p-phenylene), or a combination thereof. 7. The method of claim 1 wherein said support comprises a polytetrafluoroethylene-coated fiberglass, silicone-coated fiberglass, polytetrafluoroethylene-coated aramid fabric, silicone-coated aramid fabric, polytetrafluoroethylene-coated steel, silicone-coated steel, a rubberized fabric, a silicone-coated paper release liner, a silicone-coated polymer film release liner, a polyethylene film, a polypropylene film, a polyester film, a nylon film, a polymethylpentene film or a combination thereof. 8. The method of claim 1 wherein said support comprises a conveyor belt. 9. The method of claim 1 further comprising repeating steps b) through d) at least once to apply at least one additional polymeric material onto the woven fabric. 10. The method of claim 1 wherein step a) further comprises applying the first polymeric material onto the woven fabric as a liquid, and wherein step b) comprises applying the second polymeric material onto the support as a liquid. 11. The method of claim 1 wherein step a) comprises applying the first polymeric material onto the woven fabric as a liquid, and wherein step b) comprises applying the second polymeric material onto the support as a liquid, and wherein the first polymeric material and the second polymeric material are dried after step c) but prior to step d). 12. The method of claim 1 wherein step a) further comprises applying the first polymeric material onto at least one woven fabric as a liquid, and wherein step b) comprises applying the second polymeric material onto at least one support as a liquid, and wherein the first polymeric material and the second polymeric material are dried after step d). 13. A method of forming a fibrous composite, which comprises: a) providing a fibrous substrate comprising a woven fabric, the woven fabric having a first liquid polymeric material on a surface thereof;b) providing a support, the support having a second liquid polymeric material on a surface thereof;c) thereafter, joining the woven fabric and the support by contacting the first liquid polymeric material with the second liquid polymeric material such that the first liquid polymeric material and second liquid polymeric material are contacted with each other while each polymeric material is wet; and thend) separating the support from the woven fabric such that at least a portion of the second polymeric material remains on the first polymeric material on the woven fabric; ande) repeating steps a)-d) at least once to produce a plurality of woven fibrous composites, and thereafter consolidating a plurality of said woven fibrous composites. 14. The method of claim 13 further comprising forming a ballistic resistant article from said consolidated plurality of woven fibrous composites. 15. The method of claim 13 wherein the first liquid polymeric material and the second liquid polymeric material are dried prior to consolidation of the plurality of said woven fibrous composites. 16. The method of claim 13 wherein the first liquid polymeric material and the second liquid polymeric material are dried during or after consolidation of the plurality of said woven fibrous composites.
