Popis: The present research aimed to study the possibility to increasing flame retardancy of polymeric composite materials reinforced by fibers by coating by a flame retardant layer represent antimony tetroxide (Sb4O6) as a coating layer (4mm) thickness to react and prevent spread of flame on surface of composite material consist of epoxy resin reinforced by Kevlar fibers and exposed this coating layer to oxyacetylene flame with different exposure intervals (10,15,20mm) and study the range of resistance of flame retardant material layer to the flames and protected the substrate .The experimental results show that a great increment in thermal resistance and flame retardancy after coating by tetroxide as well as rising flame resistance increased exposure distances to flame . Determination the percentage contribution effects of main factors were time , exposure interval ,and noise variables (error) to the variability of the surface temperature at significant level (α=0.05) .Results show that the percentage of main factors were :time=63.15% , exposure interval=14.81% and noise variables=22.04%.
