The invention relates to a carbon fiber reinforced polypropylene composite material and a preparation method thereof. The carbon fiber reinforced polypropylene composite material comprises the following components in percentage by mass: 45-70% of high-crystalline polypropylene, 15-30% of recycled carbon fiber treated by a sizing agent, and a compatilizer. The preparation method comprises the following steps: treating the recycled carbon fibers by adopting a sizing agent to obtain the recycled carbon fibers treated by the sizing agent; adding high-crystalline polypropylene and a compatilizer from a main material port of production equipment, and adding the recycled carbon fibers treated by the sizing agent from a side material port of the production equipment; and carrying out melt blending on the added materials through production equipment, and then carrying out extrusion granulation to obtain the carbon fiber reinforced polypropylene composite material. According to the scheme provided by the invention, the lightweight design requirements of high strength and high modulus of automobile parts can be met.
