The creation provides a composite fabric and a preparation method thereof. The method comprises the following steps: providing a fabric layer and a membrane layer, where the melting point of the fabric layer is higher than the membrane layer; abutting the fabric layer and the membrane layer against each other to form a laminated structure; at first, heating the laminated structure at a preheating temperature, and then at a hot pressing temperature and a hot pressing pressure, heating, pressurizing and bonding the laminated structure to obtain a bonding structure, where the preheating temperature and the hot pressing temperature are greater than or equal to the melting point of the membrane layer and lower than the melting point of the fabric layer, the preheating temperature is lower than the hot pressing temperature, and the hot pressing pressure is between 0.1 kg/cm2 and 100 kg/cm2; cooling the bonding structure to obtain a composite fabric. Unnecessary to use the organic solvent, the preparation method thu
