Point of the Proposed Technology
・Use of thermoplastic composite fiber reinforced materials enables a substantial weight reduction compared to use of high-tension steel sheets or aluminum materials
・Stampable molding has enabled change in thickness, formation of ribs, etc. according to a required shape, thus realizing integrated molding.
・Enhancement of strength by the technology for flowing continuous fiber materials into every corner of a mold
・Insert molding of metal fittings or the like is also possible

Effect(s)
・Weight reduction by 30 to 45% in comparison with cast aluminum wheels
・Significant shortening of molding time in comparison with carbon fiber reinforced thermoplastic composite (CFRP ) wheels
・It is possible to make an integrated structure from a bonded structure with more parts in comparison with a CFRP wheel (by reduction of the number of parts and reduction/elimination of the bonding process, etc.)

Conventional Technology
New Technology
☆It has realized integrated molding, at a shot, of a CFRTP (carbon fiber reinforced thermoplastic composite) carbon wheel by stamping molding.
☆Weight reduction by 37% has been achieved in addition to high mechanical strength that passes the aluminum wheel standards (the JWL standard).

| Technical Problems | ・Using thermoplastic composite fiber materials, high-strength and lightweight members are realized, which was impossible by injection molding.
・Since it allows the consideration of molding parts not in units of sub-parts but in units of welded and assembled products, a substantial weight reduction and reduction of the number of parts can be expected. | ||||
