Abstract

Aluminum hydroxide as a coating layer of (4mm) thickness was used to increase the fire retardancy for advanced composite material consist of polyvinyl chloride (PVC) reinforced by carbon fibers .The resultant composite was exposed to a direct gas torch flame with flame exposure intervals 10,15,20mm, and study the range of resistance of retardant material layer to the flames and protected the substrate . The Method of measuring the surface temperature opposite to the flame was used to determined the heat transferred to composite material.
