The invention provides a microwave curing formation method for a laminated plate made of carbon fiber/epoxy resin composite materials. The microwave curing formation method for the laminated plate made of the carbon fiber/epoxy resin composite materials comprises the steps that a laid carbon fiber/epoxy resin prepreg laminated plate is placed in a vacuum bag, the upper/lower surface of the laminated plate is isolated from the inner wall of the vacuum bag through a plate mold, and the interior of the vacuum bag is vacuumized, so that the laminated plate is compacted by means of external atmospheric pressure; and then under the condition that the vacuum degree in the vacuum bag is maintained, microwave curing formation is conducted under at least one stepwise-increasing power, wherein the microwave frequency range is 2.25-2.65 GHz, the microwave power range is 40-400 W, and the total microwave radiation time is 50-100 min. In this way, the obtained microwave curing-formed carbon fiber/epoxy resin laminated plate has the characteristics of being smooth in surface and good in forming quality; and meanwhile, compared with a traditional thermocuring method, the cycle of the curing process is obviously shortened while uniform and complete curing is guaranteed, and approximate or higher glass-transition temperature and compression strength are achieved.
