Abstract

A core is made of a biodegradable material, reinforcing fibers and non-hardened resin are laminated on the core so as to form a fiber-reinforced composite material. Then, the fiber-reinforced composite material is hardened, and then biochemically active substances, such as microorganisms and enzymes, are brought into contact with the core so that the core is biochemically degraded and removed.
