Bond Performance of Carbon Fiber-Reinforced Polymer Bar The dual function of a carbon fiber-reinforced polymer (CFRP) bar working as reinforcement and impressed current cathodic protection (ICCP) anode for reinforced concrete structures has been proposed and researched in this paper. The ICCP tests with different current densities and polarization durations were first conducted for the concrete with high chloride content.
EFFECT OF ADHESIVE STIFFNESS AND CFRP GEOMETRY ON The effects of CFRP geometry, the width of the strip to the width of the soffit of the beam ratio (bf/b), and adhesive shear stiffness on the behavior of fatigue loaded specimens were investigated.Four of the retrofit specimens failed due to fatigue-induced internal reinforcement rupture prior to
To develop a high-performance, lightweight cross-laminated timber (CLT) floor, this study tested the delamination performance between carbon fiber-reinforced plastic (CFRP) and CLT and the bending performance of a CFRP composite CLT that was differently reinforced according to the shape of CFRP.

Effects of mechanical properties of adhesive and CFRP on The determination of key parameters in the bond strength model remains debatable. We studied the bond behavior between CFRP and steel, focusing on the effects of different types of epoxy adhesive and CFRP on the failure modes, bondslip relationships, and bond strength parameters.
The failure mode and fatigue life were used to evaluate the fatigue performance of the CFRP reinforced steel beam. Due to the repeated load, the bridge structure often leads to structural failure due to material fatigue. The fatigue life of the material is related to the magnitude of the repeated load value.
Fatigue strength evaluation and fracture behavior of Recently, the behavior of multi-material structural adhesives has been studied for civil, automotive and aerospace applications. In that sense, Galvez et al , presented a study of the behavior of adhesive joints of steel with carbon fiber reinforced polymers (CFRP) for its application in bus structures.
Flexure Performance of Externally Bonded CFRP Plates This paper investigates the flexural behavior of CFRP plate-strengthened concrete structures. Specimens of the CFRP plate-reinforced beam were designed and tested by the four-point flexural test. The load-deflection relationship, failure modes, and crack propagation were analyzed. The results showed that the postcracking stiffness and bearing capacity of the test beams can be improved by the
Previous studies have shown that the thickness of the adhesive layer is one of the factors affecting the overall effectiveness of the retrofit. In this paper Nondestructive Evaluation (NDE) method of infrared thermography (IRT) is used to investigate the thickness of the adhesive layer bonding a CFRP plate to a concrete structural element surface.

Study of Cryogenic Mechanical Strength and Fracture The initial failure mode of double-lap specimens was also discussed from the results by strain/stress analysis. And also the cryogenic fracture performance of bonded structure between CFRP using AF163-2K is examined. The tensile Mode-I and shear Mode-II fracture strengths of CFRP/AF163-2K bond joints are evaluated at room temperature and cryogenic
The effects of temperature and adhesive thickness on the strength were clarified from the results. It concluded that EA9394 cured at room temperature is the overall best performing adhesive for CFRP applications at cryogenic temperatures. The initial failure mode of double-lap specimens was also discussed from the results by strain/stress analysis.
Treatment of CFRP by IAR method and its effect on the For the FMLs treated with sandblasting, it mainly shows adhesive failure between epoxy and aluminum alloys, while the cohesive failure became dominant failure modes for micro-arc oxidation treated Bond Behavior between Heat-Damaged Concrete and the reinforcement by CFRPs is mainly governed by the behavior of the CFRPconcrete bond. When this bond is not strong enough, de-bonding occurs, which is a disadvantageous brittle failure . Research has been conducted to study the behavior of the CFRPconcrete bond-slip and its mode of failure at the adhered elements.
