EXPERIMENTAL STUDY ON BOND STRENGTH OF CONTINUOUS CARBON FIBER SHEET

An experimental study on bond strength of Continuous Fiber Sheet (CFS) was conducted. Based on the experimental results the bond strength and various factors are clarified. Bond strength does not increase with bond length for bond length longer than 100mm. As CFS stiffness increases, the maximum local and average bond stresses at delamination increase and CFS strain gradient decreases. CFS with a narrower width has a bond strength greater than that with a wider width. Non-uniform loading decreases the bond strength, however anchor steel plate with tensioned bolt increases it due to the bond between steel plate and CFS and confinement from the bolt. From the observed bond stress in CFS, the equation to predict the maximum local bond stress was proposed.
