The invention relates to the field of carbon materials, in particular to a carbon whisker reinforced porous glass carbon material and a preparation method thereof.The carbon whisker reinforced porous glass carbon material is prepared by taking thermosetting phenolic resin as a precursor, adding aluminum oxide powder and performing heat treatment under the high-temperature condition in one step. According to the formed carbon whisker reinforced porous glassy carbon material, graphite flake layers of a glassy carbon part are wound and staggered, and graphite flake layers of a carbon whisker part are arranged in order and respectively correspond to an amorphous structure and a crystalline structure; two different forms of carbon materials are simultaneously generated through a one-step method, and the materials are pure carbon crystalline whisker-amorphous glassy carbon composite materials. The raw materials are simple and easy to obtain, the process cost is low, and the final product carbon whisker reinforced p
