摘要
结合工程实际情况,阐述了碳纤维布剥离问题的一些重要概念,并对面内剪切试验模型进行改进,分析了碳纤维布剥离机理,推导了有效锚固长度和剥离承载力计算公式。计算公式中各参数物理意义明确,公式易于理解,计算结果与已有的试验结果吻合较好。
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.
