However, these rivet fastening processes have several disadvantages, including delamination during drilling, increased weight, galvanic corrosion with metallic rivets, and thermal expansion mismatch. Here, the authors develop a hierarchical carbon fiber reinforced thermoplastic (CFRTP) rivets using MWCNT for high strength and enhanced electrical/thermal conductivity, achieving 907 S/m and 0.750 W/m center dot K, respectively. The conductive network of MWCNT and carbon fiber enabled the induction heating-assisted fastening process. The optimal hierarchical structure and fastening process condition were investigated using a development framework with numerical modeling and experiments. The fastened CFRTP rivets showed a maximum of 35 % higher bearing strength than conventional aluminum rivets, with a 43% weight reduction. English Pergamon Press Ltd.
