This invention belongs to the field of ablation-resistant thermal insulation composite material preparation technology, specifically relating to a polyacrylonitrile-based hollow carbon fiber for thermal protection materials and its preparation method. The invention first pre-oxidizes porous polyacrylonitrile precursor fibers to obtain porous pre-oxidized fibers. Then, phenolic resin is coated onto the surface of the pre-oxidized fibers through solution polymerization. After impregnation in an organosilicon source solution, rapid Joule heating at high temperature deposits both phenolic carbon microspheres with excellent ablation resistance and a silica coating on the fiber surface, forming a unique hollow carbon fiber structure with excellent thermal insulation properties. This solves the problem that polyacrylonitrile-based carbon fibers cannot simultaneously achieve both thermal insulation and ablation resistance. The thermal conductivity of the polyacrylonitrile-based hollow carbon fiber prepared by this method is about 17% lower than that of porous polyacrylonitrile carbon fibers prepared by traditional carbonization methods, making it applicable to the field of integrated ablation-resistant thermal protection materials.
