In order to improve the flame retardant property and ablation property of silicone rubber coated fabrics, the new flame retardant silicone rubber coated fabrics were made by adding the flame retardant in the silicone rubber, and the flame retardant property and ablation property of them were tested and comparatively analyzed with military silicone rubber coated fabrics. The result shows that the flame retardant property of new flame retardant silicone rubber coated fabrics W-1 and W-2 are better than military silicone rubber coated fabrics J-1 and J-2 obviously with the oxygen index higher; the ablation property of two kinds of silicone rubber coated fabrics are similar, the temperatures of discontinue heating of the former are lower, but the highest temperatures are higher, and the ablation phenomenon are similar.
