Abstract

The aim of this paper is to use inorganic fire retardant mixture consist of zinc borate- antimony trioxide to increase the fire retardancy for advanced composite material consist of araldite resin reinforced by carbon-Kevlar fibers .In first stage a surface layer from zinc borate as a coating layer of (4mm) thickness was used. Then, this system was exposed to a direct Oxyacetylene torch flame with flame exposure intervals 10,20mm, and study the range of resistance of retardant material layer to the flames and protected the substrate. The second stage was to form a hybrid fire retardant by added antimony trioxide with various amount (10%,15%,20%,25%,30%) to zinc borate for enhance the action of this material to react flame and exposure this hybrid material to same flame temperature and exposure intervals. Method of measuring the surface temperature opposite to the flame was used to determine the heat transferred to composite material. The best results were obtained with large exposed interval and large percentage from protective layer which is zinc borate with (30%) antimony trioxide.
