NOVELTY - Preparing a carbon/boron carbide composite material involves providing a carbon compound, a carbon fiber, a boron compound, and a binder to perform a pretreatment mixing procedure to form a precursor, putting the precursor into a spray granulator for performing a granulation process, and mixing the precursor to form an injection material with a uniform composition, feeding the injection material into an injection molding machine for performing a compression molding process, thereby forming a carbon compound/boron compound green body, and subjecting the carbon compound/boron compound green body to a two-stage heat treatment method to obtain the carbon/boron carbide composite material. USE - Method for preparing a carbon/boron carbide composite material, used in industrial production. ADVANTAGE - The Method has light weight, high hardness, low cost, high strength, and high thermal shock resistance. It has simple operation, high production efficiency, high toughness, good friction, and wear performance.
