A method of making an integrally stiffened article, comprising the steps of: providing at least two elongated mandrels; individually wrapping each of said at least two mandrels with a first layer of a reinforced polymer composite material extending at least once around each of said at least two mandrels; disposing said at least two mandrels in a predetermined adjacent orientation; overwrapping a second layer of a reinforced polymer composite material at least once around said at least two mandrels to form a subassembly; providing at least one additional elongated mandrel; individually wrapping said at least one additional mandrel with a first layer of a reinforced polymer composite material extending at least once around said at least one additional mandrel; disposing said at least one additional mandrel in adjacent relation with said subassembly; overwrapping a third layer of reinforced polymer composite material around said subassembly and said at least one additional mandrel to form an assembly; and curing said assembly to form an article having a plurality of internal integral stiffeners having common fiber reinforcement, with each of said internal integral stiffeners having fiber reinforcement common to said third layer of reinforced polymer composite material.
