Preferably, the carbon fiber cloth layer is formed by weaving carbon fiber warp yarns and carbon fiber weft yarns. The woven structure of the carbon fiber cloth layer enables the polyester fabric to have good tensile resistance.

Preferably, the carbon fiber warp and the carbon fiber weft are both strips and have the same width. The strip is woven and combined, and can reduce the gap than using the round wire, prevents that external unfavorable substance from getting into to harm fire-retardant layer, has the guard action to fire-retardant layer.

Preferably, the thickness of the asbestos layer is greater than or equal to 1/2 of the thickness of the flame-retardant layer. After the asbestos layer is enough, the flame retardant effect is good.

Preferably, the polyester cloth layer and the carbon fiber cloth layer are compounded by hot pressing through an adhesive. The carbon fiber cloth layer is compounded with the polyester cloth layer through the adhesive in a hot pressing mode, and the polyester cloth layer is firmly attached to the carbon fiber cloth layer, so that the heat insulation effect is good.

The utility model has the beneficial effects that: the flame-retardant layer is not easy to burn to achieve the flame-retardant effect, and the carbon fiber cloth layer is not easy to burn and transfer heat, so that the purpose of good heat insulation effect is achieved; the fire resistance is good, and the use is environment-friendly and safe; the tensile property is good; has protective effect on the flame-retardant layer.
