A composite material preparation system comprises a sealed reaction kettle for containing reactants and base materials; temperature and pressure detecting units for detecting the temperature and pressure inside the reaction kettle; and a heating unit for hydrothermally induced heating, based on the detected temperature and pressure values. The heating unit comprises an induction coil, an induction heating device, and a control mechanism for controlling the generation of an induction frequency of the induction heating device. The reaction kettle is located in the induction coil, both ends of the induction coil are mounted on an outer wall of the induction heating device, and the induction coil and the induction heating device have circulating water introduced inside. The device can prepare a composite material having good interface bonding, by utilizing induced heating under the premise of controllable temperature and pressure, and by utilizing the characteristic that the reactants themselves are heated.
