Abstract

Aimed at the low joint efficiency arising from the unidirectional pultruded fiber composites application to civil and transportation field, it was put forward a new type of joint of FRP composite:binding-adhesive joints.Experiments were conducted on three types of joints, including binding-adhesive joints, bolt joints and adhesive joints.The experimental results proved that binding-adhesive joints had a high joint efficiency factor;the bearing capacity was 3.8 times of the bolt joints, 3.5 times of the adhesive joints.Based on the load-displacement curve obtained from experiments, a comparative analysis of stiffness and ductility of the three types of joints was made.According to the experimental phenomena and results, the analysis of the working mechanism of binding-adhesive joints was made.
