The invention discloses an integrated machining process for a carbon fiber shell of an unmanned aerial vehicle. The integrated machining process comprises the following steps: (1) modeling the shell of the unmanned aerial vehicle; (2) preparing an upper mold, a lower mold and a silicone rubber air bag; (3) inflating the silicone rubber air bag; (4) smearing demolding wax; (5) laying carbon fiber cloth on the outer surface of the silicone rubber air bag, and brushing resin; (6) repeating the step (3) for multiple times; (7) putting the silicone rubber air bag into the lower mold, and oppositely combining the upper mold and the lower mold up and down and fixing the upper mold and the lower mold through a fixture; (8) carrying out secondary inflation on the silicone rubber air bag; (9) deflating the silicone rubber air bag after normal-temperature curing; and (10) taking out the silicone rubber air bag and the formed carbon fiber shell. The integrated machining process for a carbon fiber shell of an unmanned aerial vehicle is easy to operate, demolding wax is not needed when the silicone rubber air bag is demolded, the technology is simple, the processing cost is low, the strength and toughness are high, and the prepared shell is integrally formed and is high in strength and light in weight.
