Mesh made of a composite material

Abstract

A mesh ( 12 ) is made of a composite material having fibers. The fibers are mutually arranged to form a weft ( 14 ) and a warp ( 16 ). The weft ( 14 ) includes at least one weft yarn ( 142 ) which has at least one fiber. The warp ( 16 ) includes at least one warp yarn ( 162 ) which has at least one fiber. In the mesh made of a composite material ( 12 ), the weft ( 14 ) and the warp ( 16 ) are mutually connected at intersection points ( 18 ) by interlacing ( 20 ).

         14 . A mesh made of a composite material comprising fibers; said fibers being mutually arranged to form a weft and a warp;
 said weft comprising at least one weft yarn comprising at least one fiber;   said warp comprising at least one warp yarn comprising at least one fiber;   wherein said weft and said warp are mutually connected at intersection points by interlacing, and   wherein said mesh further comprises a binding agent, said weft and/or said warp being impregnated with said binding agent in predetermined impregnation zones so that some portions of weft yarns and/or some portions of warp yarns comprise portions of virgin fibers.   
     
     
         15 . The mesh of  claim 14 , wherein said predetermined impregnation zones comprise the intersection points and act as interlacing. 
     
     
         16 . The mesh of  claim 14 , wherein said weft and said warp have a direction substantially perpendicular to each other. 
     
     
         17 . The mesh of  claim 14 , wherein said weft and said warp have directions mutually inclined by an angle smaller than 90°. 
     
     
         18 . The mesh of  claim 14 , wherein said fibers comprise synthetic organic fibers, natural organic fibers, inorganic fibers, and/or metallic fibers. 
     
     
         19 . The mesh of  claim 18 , wherein said synthetic organic fibers are aramid, polyester and/or polyparaphenylene benzobisoxazole (PBO) fibers; said natural organic fibers are cotton, hemp, linen, sisal, bamboo, wood, wool, and/or silk; said inorganic fibers are glass, carbon, basalt, and/or quartz; said metallic fibers are stainless steel, carbon steel, copper, brass, aluminum, and/or titanium. 
     
     
         20 . The mesh of  claim 14 , wherein said binding agent is a thermosetting or thermoplastic resin. 
     
     
         21 . The mesh of  claim 20 , wherein said thermosetting resin is selected from the group consisting of resins of the vinyl-ester, polyester, bisphenolic and acrylic resins and the thermoplastic resin is selected from the group consisting of type PVA, PP, Pen resins. 
     
     
         22 . The mesh of  claim 14 , wherein the weft yarns are impregnated with said binding agent and preformed. 
     
     
         23 . The mesh of  claim 14 , wherein the warp yarns comprise fibers twisted about an axis of the warp yarn. 
     
     
         24 . The mesh of  claim 14 , wherein the warp yarns are impregnated with the binding agent at intersections with the weft yarns, and the warp yarns comprise virgin fibers between one intersection and the other. 
     
     
         25 . The mesh of  claim 14 , wherein said predetermined impregnation zones are configured to leave portions of weft yarns and/or portions of warp yarns made of virgin fibers, which allow the mesh to be bent in inclined directions relative to a direction of respective portions of weft yarns and/or portions of warp yarns. 
     
     
         26 . The mesh of  claim 14 , wherein at least part of the weft yarns comprise fibers of different materials to make mesh zones with predetermined technical characteristics, and/or in a mesh wherein at least part of the warp yarns comprise fibers of different materials to make zones of the mesh with predetermined technical characteristics.
