The synthesis of reaction flame retarding unsaturated polyester resin and the flame retarding mechanism are investigated. By taking the synthesis flame retarding unsaturated polyester resin as a base material,glass fibers as reinforced material, under the condition of adding graphite or carbon black respectively, the composites were manufactured. The flame retarding and antistatic properties are also studied. In the experiment, bromidebearing flame retarding resin decomposed under a high temperature. Compound HBr was set out and retarded or stopped the flame. High concentration of HBr gas wall was formed between gas and solid phrases, which decreased flame. The results show that antistatic property of carbon black is higher than that of graphite. Adding a threshed value of 1% carbon black into composite, the antistatic property is at its highest value.
