Unsaturated polyester (UPE) was mixed with fire retardant additives including antimony trioxide (Sb2O3), aluminum hydroxide Al(OH)3, chlorinated paraffin (CPs). The composite materials burning rate (Vc) was determined according to ASTM D635-14 and UL94-HB standards. The thermal decomposition behavior of CP-KUFP was investigated by carrying out the thermogravimetry analyzed method (TGA). Results: The optimal mixing formula was determined with kevlar fiber 35 wt%, flame retardant 10 wt%, MEKP curing agent 0.55 wt% and UPE resin content 54.45 wt%. CP-KUFR material was achieved UL-94HB standard; Burning rate zero; With standing to 800oC; The low weight change process was shown from 11 %/mg to 16 %/mg. Keywords: Kevlar fiber; Flame retardant additives; Composite; Unsaturated polymer resin. 1. INTRODUCTION Composite materials are increasingly used in the world because of its outstanding properties. UPE resins have been used as a substrate in composite materials for use in military and a number of industries such as construction, aerospace, transportation. due to their lightweight properties, good corrosion resistance and performance. However, polyester is very easy to ignite, so it is necessary to research to develop fire retardant for UPE composite material. At present, the method of efficiency and convenience is to enhance the thermal decomposition .
