Abstract:
A method of manufacturing a structure made of fiber-reinforced composite material by using a mold made of a biodegradable material, comprising:a step for forming said mold by using a material containing biodegradable polymers; a step for laminating said fiber-reinforced composite material on said mold; a step for hardening said fiber-reinforced composite material; a step for removing said mold by dint of biochemical degradation; said step for forming said mold by using said material containing said biodegradable polymers is to form a multiplicity of spherical cores; said step for laminating said fiber-reinforced composite material on said mold includes a step for forming reinforcing-fiber spherical members by laminating reinforcing fibers and non-hardened resin on the outer surfaces of said spherical cores; and a step for filling a multiplicity of said reinforcing-fiber spherical members into another mold so as to bring said reinforcing-fiber spherical members into close contact with one another.
