| Abstract | ||
| Zinc borate was added as a surface layer of (4mm) thickness on the surface of araldite resin reinforced by woven roving carbon-kevlar fibers .This system was exposed under different exposure intervals (10,15, and 20mm) to a direct flame which generated from oxyacetylene and gas flame (3000ºC,2000ºC) respectively, and study the range of resistance of flame retardant material layer to the flames and protected the substrate . Surface temperature opposite to the flame method was used to measuring the temperature transferred through this system. The experimental results show that a great increment in thermal resistance and flame retardancy after coating by zinc borate and the best percentage was (20%) from zinc borate, as well as rising flame resistance increased exposure intervals to flame | ||
