PROBLEM TO BE SOLVED: To provide a resin infusion process enabling a manufacturing method of a high quality composite part. SOLUTION: The resin infusion process includes a step of evacuating a resin supply tank to pressure lower than the atmospheric pressure, and a step of controlling a net molding pressure by using a cyclic compaction. Thereby, a resin infusion process and particularly a vacuum assisted resin transfer molding process is controlled more suitably. Thus, aerospace grade fiber-reinforced resin composite material having fiber volume fraction and tool side surface finishing, equally matched to or exceeding a product manufactured by using an autoclave, by more suitably controlling the resin infusion process and by particularly controlling a vacuum assisted resin transfer molding process, can be produced.
