The invention relates to a TiC/SiC/Al composite material. An outer layer of the TiC/SiC/Al composite material is a TiC reaction layer, and the interior of the TiC/SiC/Al composite material is a SiC/Alcomposite layer. A preparation method of the composite material comprises the following steps of (1) preparation of an aluminum alloy, specifically, the aluminum alloy comprises the elements of, by mass, 50-90% of Al, 5-20% of Ti and 5-30% of Si; (2) pretreatment of SiC ceramic; (3) reaction infiltration process, specifically, the aluminum alloy prepared in the step (1) is smelted in a box-type furnace to obtain aluminum alloy liquid, the SiC ceramic processed in the step (2) is immersed into the aluminum alloy liquid and put into the box-type furnace for heat preservation, the infiltrating temperature is1150-1200 DEG C, the infiltrating time is 0.5-8 h, a sample is taken out and cooled to room temperature to obtain the TiC/SiC/Al composite material. The TiC/SiC/Al composite material hasgood fracture toughness under the premise of ensuring bending strength, and the preparation process is simple, and the TiC/SiC/Al composite material is suitable for large-scale industrialized production.
