Abstract
A friction stir blind riveting (FSBR) process is used to fabricate joints of carbon fiber-reinforced polymer composite (CFRP) and aluminum alloy AA6111 sheets in a lap shear configuration. Given the 9,000 rpm spindle speed upper limit of conventional computer numerically controlled machines, the maximum feed rate for FSBR joining CFRP to itself is found to be 120 mm min−1 above which quality issues such as cracking of the CFRP sheet predominate. However, the maximum feed rate during dissimilar joining of CFRP to AA6111 can be 420 mm min−1 when the CFRP top sheet is supported by the AA6111 bottom sheet. The maximum lap shear tensile load of the joints shows little dependence on the spindle speed and feed rate during FSBR. The different stack-up sequences of the CFRP and AA6111 lead to different maximum loads, displacements to fracture, and locations of fracture initiation, i.e., in the CFRP vs. in the AA6111.
