The invention belongs to the technical field of material preparation, and particularly relates to a flame-retardant arc-proof composite fabric and a preparation method and application thereof. The composite fabric is prepared by the following method: firstly, synthesizing polybenzimidazole-containing polyamide fibers in a reaction kettle; and then blending the polybenzimidazole-containing polyamide fiber, meta-position aramid fiber and flame-retardant viscose to obtain the composite fabric. The prepared composite fabric is good in flame retardant property, good in color fastness, excellent in washing resistance and good in water resistance and air permeability, and the tensile strength of the fibers is improved. The fiber prepared by the method is not molten during combustion, small in shrinkage rate and high in dilutability, and the prepared fabric is good in comfort. 本发明属于材料制备技术领域，具体涉及一种阻燃防电弧复合面料及其制备方法、应用。所述复合面料通过以下方法制备而成：首先在反应釜中合成含聚苯并咪唑的聚酰胺纤维；然后将含聚苯并咪唑的聚酰胺纤维、间位芳纶、阻燃粘胶进行混纺即得复合面料。本发明制备的复合面料阻燃性能好，且色牢度好，耐洗涤性能优
