The invention discloses a method for bonding carbon fiber / phenolic-nitrile rubber materials, and belongs to the field of the manufacturing of a solid rocket engine insulator, and aims at solving the bonding problems of an engine housing, a first EPDM insulation material, a carbon fiber / phenolic-nitrile rubber materials and a second EPDM insulation material and improving the structural reliability. The method mainly comprises the steps of preparation, coating, prefabrication, cleaning, glue coating, setting, thermal pre-pressing, flaw detection, curing and the like. The structural integrity of the engine housing, a first EPDM insulation material, the carbon fiber / phenolic-nitrile rubber materials and the second EPDM insulation material are ensured by using a secondary bonding method, a secondary curing mode, a prefabrication forming method, a stepped temperature rising / dropping mode and other methods; the method has no de-bonding, air-entraining air hole and other quality problems, completely can meet the design requirements, and ensures the safety and reliability of a system.
