The invention provides a carbon fiber preform, a preparation method thereof, a brake disc and a vehicle. The tensile strength of the carbon fiber preform can be enhanced. The carbon fiber prefabricated body comprises a first side and a second side, the first side and the second side are oppositely arranged in the thickness direction of the carbon fiber prefabricated body, the carbon fiber prefabricated body comprises a plurality of carbon fiber layers arranged in a stacked mode, a plurality of interlayer fibers are arranged between every two adjacent carbon fiber layers and extend in the thickness direction of the carbon fiber layers, and the first side and the second side are oppositely arranged. In the direction from the first side to the second side, the density of the interlayer fibers is firstly increased and then reduced.
