Abstract

Journal of Thermoplastic Composite Materials, Ahead of Print.
To enhance CFRP-aluminum alloy thin plate joint strength, this study proposes a novel hybrid riveting method. It involves 3D-printing multi-row micro-metal rivets on aluminum substrate, embedding them into carbon fiber fabric, and co-curing via vacuum-...
