  ABSTRACT: This study aims to investigate the possibility of improving the flame Retardancy for the hybrid composite material consisting araldite resin (CY223). The hybrid composite was reinforced by hybrid fibers from carbon and Kevlar fibers on woven roving form (45o -0o), by using a surface layer of 4mm thick of Zinc Borate flame retardant. Afterward, the structure was exposed directly to gas flame of 2000oC due to 10 mm and 20mm exposure interval. The retardant layer thermal resistance and protection capability were determined. The study was continued to improve the performance of Zinc Borate layer mixed by 10%, 20% and 30% of Antimony Trioxide. To determine the heat transfer of the composite material the opposite surface temperature method was used. Zinc Borate with (30%) Antimony Trioxide gives the optimized result of the experiment.
