Abstract:Based on the engineering practice, several important concepts of CFRP de-bonding were introduced, and an in-plane shear test model was improved. The de-bonding mechanism of CFRP was analyzed. The calculation formulae of the effective anchorage length and the de-bonding capacity were derived. In the derived calculation formula, the physical meaning of each parameter is clear, and the formula is easy to be understand. The calculation results agree well with the exsiting test results.
Keywords:CFRP; de-bonding;effective anchorage length;de-bonding capacity
