Continuous compression molding machines (CCMMs) and methods of continuous compression molding a consolidated thermoplastic matrix composite material are disclosed herein. The CCMMs include a mold, a heat zone heating structure, a consolidation zone heating structure, and a stress relaxation zone heating structure. The CCMMs also include a press structure, a demold structure, and a supply structure. The methods include providing a thermoplastic matrix composite material (TMCM) that includes a thermoplastic material to a CCMM. During the providing, the methods also include heating the TMCM within a heat zone of the CCMM, cooling and consolidating the TMCM within a consolidation zone of the CCMM, relaxing stress within the TMCM within a stress relaxation zone of the CCMM, demolding the TMCM within a demold zone of the CCMM at a mold temperature that is greater than a glass transition temperature of the thermoplastic material, and periodically compressing the TMCM.

A tool for forming a part includes a first tool portion including a first tool surface. The tool further includes a second tool portion comprising a second tool surface facing the first tool surface, wherein the first tool surface and the second tool surface define a tool chamber for forming the part. The tool further includes a bladder subassembly disposed in the tool chamber between the first tool surface and the second tool surface. The bladder subassembly includes a plurality of inner bladders disposed within tool chamber, wherein each inner bladder of the plurality of inner bladders includes an inner bladder chamber that is independently inflatable to selectively apply pressure to the part. The bladder subassembly further includes a bladder cover disposed over the plurality of inner bladders within the tool chamber to provide a barrier between the plurality of inner bladders and the part.

A composite manufacturing system and method are provided. The composite manufacturing system comprises a press and a bladder. The press has an upper portion having a desired shape for a composite structure and a lower portion configured to receive layers of composite material. The bladder is associated with the upper portion of the press and is configured to reach a superplastic state when heated such that the bladder forms to the composite structure by applying heat and pressure to the layers of composite material. The bladder cools without appreciable shrinkage, applying a desired amount of pressure to the composite structure during the entire cooling cycle. Once one composite structure is formed using the bladder, the bladder may be reused to form similar structures.
