Point of the Proposed Technology
Previously, in 3D molding a thermoplastic CFRP laminate, there was a problem that a laminate using fabric material as the base material is subject to creasing because of lack of elasticity. By developing a laminate using knitted material as the base material, a CFRP laminate with excellent forming capabilities can be acquired.
Effect(s)
3D moldings of thermoplastic CFRP
Conventional Technology
〇 3D molding sample of a CFRP laminate using carbon fiber fabric as the base
Creasing occurs during 3D molding.
Creasing occurs during 3D molding.
New Technology
〇 A CFRP laminate using carbon fiber knitted material as the base
Point: Since the base fabric has elasticity, the material is less subject to creasing during molding.
However, it is difficult to produce knitted material using carbon fiber. Carbon fiber intermediate material that can be easily knitted must be developed.

| Example of Application | ・Health care products
・Sports equipments ・Automobile parts, etc. | ||||
| Technical Problems | ・Improved adhesion between carbon fiber and thermoplastic resin
・The strength of CFRP knitted fabric is inferior to CFRP fabric. It is important to consider the balance between three-dimensional formability and physical properties such as strength for right situations. | ||||
| Collaborator needed to Improve | Company that will work on the development of a 3D molding technology for CFRP laminates using knitted material as the base in cooperation with the center
