The invention belongs to the technical field of composite material processing, and particularly relates to a composite material preparation device and method.The composite material preparation device comprises a material storage barrel and a forming mold which can relatively extrude and rotate, and a containing cavity for storing a core material and a coating material is formed in the material storage barrel; a first opening communicated with the accommodating cavity is formed in the end part of the storage barrel; the forming die is inserted into the containing cavity from the first opening, the end face of the inserting end of the forming die is sunken from the periphery to the center to form a friction heat production face, and a forming window penetrating through the forming die is formed in the center of the end face. According to the device, based on the principle that thermoplastic rheology is generated through friction, the prepared composite material is small in internal stress and excellent in perfo
