摘要
进行了CFRP与钢板的粘结性能试验研究,以期了解2种材料的粘结性能以及底胶和横向CFRP等因素对试件承载力和刚度的影响。研究结果表明:在纵向CFRP断裂前,不论是否使用底胶以及是否粘贴横向碳纤维织物,纵向CFRP和钢板都能保持协同工作;试件的荷载—应变曲线可以划分为3个阶段,即弹性阶段、弹塑性阶段和下降段;在其它条件相同的情况下,底胶和横向CFRP对试件的承载力和刚度并无显著影响。
Cohesive between CFRP and steel plate is experimentally studied, in order to understand the cohesiveness between CFRP and steel plate and the influences of under glue and transverse CFRP on bearing capacity and stiffness of the specimens. It is found that the longitudinal CFRP and the steel plate could cooperate before the longitudinal CFRP failing whether under glue and transverse CFRP are used; load - strain could be defined as 3 stages, elastic stage, elastic - plastic stage and descending stage; if other factors are the sane, under glue and transverse CFRP have no significant influences on specimen＇ s bearing capacity and stiffness.
