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).

Technology Deployment and Cooperation

Development Stage	Development Stage (to be completed in 2018/10; progress: 90%)
Intellectual Property Right	None
Joint Researchers (their role)
Example of Application	Automobiles, aircrafts, medical devices, general industrial parts, etc.
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.
Collaborator needed to Improve	Universities and businesses having knowledge about composite fiber flowing technologies or material technologies Public institutions and research organizations including universities having strength assessment technologies andequipment
