Plasticity is crucial for structural components,not only to prevent brittle failure but also to enhance their impact resistance and seismic capabilities.Traditional cement-based materials are brittle and easily cracking,whereas fibers as reinforcing materials are increasingly favored for their toughening and crack resistance properties.Based on carbon fiber reinforced polymer(CFRP)and basalt fiber reinforced polymer(BFRP),this study investigated the bond plasticity performance at the concrete interfaces through double shear tests.The results show that the bond between basalt fibers and concrete exhibits superior plasticity.Due to its excellent mechanical properties and affordable cost,BFRP is gradually becoming more visible to the public.The findings of this paper are of significant importance for similar future studies on fiber-reinforced materials and their bond plasticity with concrete interfaces.
