Composite material preparation system and method effectively improving composite material interface bonding

A method for preparing a composite material with a composite material preparation system, the composite material preparation system comprising:

• a sealed reaction kettle for containing reactants and matrix materials;
• a temperature detecting unit for detecting the temperature in the reaction kettle;
• a pressure detecting unit for detecting the pressure in the reaction kettle;
• and
• a heating unit for hydrothermal induction heating of the reaction kettle, based on a temperature value detected by the temperature detecting unit and a pressure value detected by the pressure detecting unit;
• wherein the heating unit comprises an induction coil, an induction heating device, and a control mechanism for controlling the induction frequency of the induction heating device, and
• wherein 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 circulating water is circulated inside the induction coil and the induction heating device;
• the method comprising the steps of:
• circulating the circulating water inside the induction coil and the induction heating device of the heating unit;
• containing the reactants and the matrix materials in the sealed reaction kettle;
• placing the reaction kettle in the induction coil;
• detecting the temperature in the reaction kettle;
• detecting the pressure in the reaction kettle;
• performing hydrothermal induction heating on the reaction kettle by controlling the induction heating device, based on the temperature value detected and the pressure value detected;
• and
• cooling the reaction kettle after the reaction to give a reaction product.
