Reducing of flammability for polymeric composite material by using flame retardants coating

Abstract EN

The low thermal resistance of polymeric materials to high temperatures considered the main limitation to used these materials in such applications required high thermal resistance, so, the present research aimed to study the possibility to increasing flame retardancy of advanced polymeric composite materials reinforced by fibers by coating by a flame retardant layer represent antimony peroxide (Sb2O4) as a coating layer (4mm) thickness to react and prevent spread of flame on surface of composite material consist of araldite resin(AY103) reinforced by woven roving carbon–Kevlar fibers (0°-45°) and exposed this coating layer to direct flame generated from oxyacetylene flame with different exposure distances (10mm, 15mm, 20mm) and study the range of resistance of flame retardant material layer to the flames and thermal resistance and flame retardancy after coating by antimony peroxide as well as rising flame resistance increased exposure distances to flame .
