Joining Fastening and joining device for thermoplastic CFRP rivet using the servo press unit

Technical Classification:
[ Joining ]
Products:
[ Equipment / Facilities ]
Keyword:
[ CFRTP ] [ joining technology ] [ rivet ] [ Servo press ]

Point of the Proposed Technology

・Base materials and part of the joint face of base materials are fastened with a thermoplastic CFRP rivet for secure joining.
・Since thermoplastic CFRP is hardly used as a fastening material, our technology is expected to bring great novelty.
・Electric servo press (manufactured by our company) is used as a fastening device for determination of load, position control and evaluation of fastening.

Effect(s)

(i) High strength: Shearing stress of 190 MPa or higher  
(ii) Simple joining technology for dissimilar materials
