A composite manufacturing system is provided. The composite manufacturing system comprises a fiber placement head, a compaction roller associated with the fiber placement head, and a temperature regulation system associated with the compaction roller. The temperature regulation system is configured to actively control a temperature of the compaction roller. The temperature regulation system comprises a number of temperature sensors, a cooling system, and a controller. The number of temperature sensors are configured to detect the temperature of the compaction roller. The cooling system is associated with the compaction roller and is configured to cool the compaction roller. The controller is in communication with the number of temperature sensors and the cooling system. The controller is configured to cool the compaction roller such that the temperature is below a threshold temperature.

Provided is a heating device including: a heating unit that heats a laminate which includes a plurality of sheet-like composite materials including reinforced fiber and thermoplastic resin, and heats, via a first contact surface disposed in contact with the laminate, the thermoplastic resin included in the laminate being in contact with the first contact surface to a softening temperature or higher; a cooling unit that cools, via a second contact surface disposed in contact with the laminate, the thermoplastic resin included in the laminate located outside of the second contact surface to a temperature lower than the softening temperature; and a pressing unit that applies a predetermined pressure to the laminate via the first contact surface and the second contact surface, the second contact surface being disposed so as to surround the first contact surface.
