Abstract

Shape memory alloy-carbon fiber reinforced composite (SMA-CFRP) is a promising material for repairing and strengthening crack-sensitive metal structures. In this paper, aiming at the anchoring problem in the process of preparing SMA-CFRP composites, a kind of bolt Anchorage made by CFRP is proposed, which optimizes the anchoring effect of SMA. Based on the finite element analysis, the simulated axial tension test of SMA-CFRP composite made by CFRP Anchorage is carried out, and the bearing capacity of the structure and the deformation and failure process of the structure are mainly studied when the Anchorage system fails. The results show that compared with the traditional bonding Anchorage system, the CFRP bolt anchoring system can effectively increase the ultimate load that SMA-CFRP composite can bear when the Anchorage system fails, which increases by 35% compared with the traditional bonding Anchorage system.
