PROBLEM TO BE SOLVED: To provide a composite container manufacturing method capable of improving strength of a composite container.SOLUTION: A composite container manufacturing system 100A for manufacturing a composite 1 having a reinforcing layer 3 comprises hardening means for heating a container intermediate 1a formed by winding a fiber bundle 10 impregnated with thermosetting resin around an outer face of a liner 2, and hardening the thermosetting resin of the fiber bundle 10. The hardening means comprises first heating means 21 for heating the container intermediate from outside, and second heating means 42 for heating the container intermediate 1a from inside. The second heating means 42 heats inside of the container intermediate 1a at higher setting temperature than the first heating means 21 at least when an excessive temperature rise phenomenon occurs. Thereby, distortion of fibers due to a difference of a shrinkage amount of resin can be restrained, so as to improve strength of the container. |
