Abstract

The application of FRP/SMA composite materials in civil engineering reinforcement has been quite extensive, and the excellent bonding between SMA wire and epoxy adhesive interface is crucial to reinforcement effectiveness. The bonding performance of Fe-SMA/epoxy adhesive interface under two types of adhesives was studied through SMA wire pull-out tests, analyzing the effects of adhesive types on failure modes, ultimate loads, and interface load-displacement relationships. The results showed that the failure modes of Sikadur-330 CN and Caben impregnated adhesive were both brittle failures of the Fe-SMA wire/epoxy resin interface adhesive layer, with Sikadur-330 CN epoxy impregnated resin exhibiting superior bonding performance, with a bonding strength approximately 2.2-3.4 times that of Caben impregnated adhesive. This study can provide a certain experimental basis for the design, preparation, and research application of FRP/Fe-SMA composite materials in civil engineering reinforcement.
