The invention discloses a preparation method for a Ti3Al-TiAl laminated composite material, relating to a preparation method for a metal laminated composite material and aiming at solving the problems of high requirement on equipment and complex process in a traditional preparation method. The preparation method for the laminated composite material comprises the following steps of: placing a Ti foil and an Al foil which are alternatively arranged in a stacking way into a vacuum hot press sintering furnace and heating to 300-500DEG C and simultaneously pressurizing; and secondly, unloading the pressure, heating the stacked foils to 600-800DEG C and maintaining the temperature, then heating the foils to 900-1300DEG C, simultaneously applying the pressure of 10-30MPa, maintaining the pressure and then cooling along with the furnace and withdrawing the die to obtain the Ti3Al-TiAl laminated composite material. According to the preparation method disclosed by the invention, the preparation of the laminated composite material can be finished at a time; a production process is simple and feasible; the requirement on the equipment is low; and the obtained laminated composite material is compact in interface bonding and is applied to aerospace turbine engine vanes, aerofoils and members of engines of high-grade cars.
