Abstract
Method of manufacturing a ribbed structure with fiber-reinforced composite material is provided. A mold for the structure is prepared having a mold surface. Non-hardened resin containing reinforcing fibers are placed on the mold surface of the structure mold. A mold for a rib is formed by using a material containing biodegradable polymers. Non-hardened resin containing reinforcing fibers are laminated on the rib mold, and then the rib mold is placed in a predetermined position on the non-hardened resin containing the reinforcing fibers tin the mold surface of the structure mold. The non-hardened resins are hardened and the rib mold is biochemically degraded wherein in the hardening of the resins, the resin hardened on the rib mold and the resin hardened on the mold surface of the structure mold are united with each other.
