1. A non-rigid composite sheet comprising in order
(i) a first component having an areal density of from 102 to 678 gsm comprising a first woven fabric of continuous filament yarns, the yarns having a tenacity of at least 11 g/dtex and a first polymeric layer, (ii) a second component having an areal density of from 40 to 170 gsm comprising an inorganic refractory layer adjacent to at least one polymeric layer, and (iii) a third component having an areal density of from 102 to 678 gsm comprising a second woven fabric of continuous filament yarns, the yarns having a tenacity of at least 11 g/dtex and a second polymeric layer, the second fabric of the third component being adjacent to the refractory layer of the second component, wherein
(a) the yarns of the first and second fabrics comprise aromatic polyamide, aromatic copolyamide, glass fiber or carbon fiber,(b) the polymer of the first polymeric layer of the first component and second polymeric layer of the third component is polyurethane, polyethylene, polypropylene, polyethylenenaphthalate, polyacrylonitrile, fluoropolymer, polyimide, polyketone, polyimide, polysulfone, polyarlene sulfide, liquid crystal polymer, polycarbonate or an ionomer,(c) the polymer of the protective polymeric layer of the second component is a polyketone, polyimide, polysulfone, polyarylene sulfide, fluoropolymer, liquid crystal polymer or polycarbonate,(d) the first polymeric layer of the first component blocks at least 95% of UV rays,(e) the first and second fabrics individually have an areal weight of from 84-508 gsm,(f) the inorganic refractory layer of (ii) comprises platelets, and(g) the composite sheet is either a sidewall or a ceiling of a cargo container or both. |
