Abstract:
This study aims to develop carbon fiber reinforced thermoplastic (CFRTP) rivet fastening process using a servo press machine and infrared or high frequency induction heating. The materials used for experiment were unidirectional carbon fiber reinforced polyamide 6 (UD-CF/PA6) rod for rivet fastener. Specimens were made from CF/PPS laminates or AISI304 stainless steel of 2.0 mm thickness. The tensile shear strength was compared by CFRTP rivet, aluminum rivet and epoxy adhesive. The effects of heating time, forming load and holding time on fastening process were investigated. The optimum CFRTP rivet fastening process condition was obtained to improve the joining strength. The contents for evaluation are heating distribution of UD-CF/PA6 rod, pressure loading behavior, cross-sectional observation after joining and tensile shear strength test. The tensile shear strength of the CFRTP rivet was 200 MPa, which was higher than aluminum rivet and epoxy adhesion. In the case of UD-CF/PA6 rivet specimen, the strength was increased significantly compared to the other fastening and bonding because unidirectional carbon fiber was located continuously within the matrix polymer. The structure where the rivet head and body are united with continuous fibers showed sufficient strength. The high availability of CF/PA6 rivet as mechanical fastener was shown from mentioned results.
