The invention discloses a molding method of a semi-closed composite structure and aims to solve the problem of difficulty in molding of semi-closed composite structures with existing molding technologies. The semi-closed composite structure is manufactured through combined use of a mold pressing technology and a vacuum bag technology, the problem about manufacturing of a common-substrate radome of a certain model of aircraft is effectively solved, the structural weight of a product is controlled, and use functional requirements of the product are met. 本发明公开了种半封闭复合材料结构的成型方法。为了解决现有成型工艺对半封闭的复合材料结构的成型困难问题，本发明通过模压技术与真空袋技术的结合使用，实现半封闭复合材料结构的制造，有效地解决了某型机共基板天线罩的制造问题，既控制了产品的结构重量，又满足了产品的使用功能要求。
