The Effect of the Setting Force on the Fatigue Resistance of a Blind Rivet Nut Set in CFRP

Weight reduction is often a key factor in modern mechanical design, therefore materials such as carbon fibre reinforced plastics (CFRP) are increasingly used and integrated within multi-material structures using adhesive technologies, which require high effort difficult to disassemble. The capability of blind rivet nut (BRN) join different without these disadvantages has created growing industrial interest the fastener. However, installing BRN CFRP laminate induces significant stress concentration plate, potentially causes damage. Given that ‘damage free’ joints demanded by industry, not considered suitable joining technique. In present research, an experimental campaign performed investigate fatigue resistance joint CFRP. It demonstrated resulting compressive after can enhance specimen. results increase potential fastener for
