CFRP-混凝土界面粘结性能试验研究

Experimental Research on the Bond Performance of CFRP-Concrete Interface

通过自设的试验方法,研究了粘结碳纤维增强塑料(CFRP)布的C20,C30,C40混凝土试件在不同的CFRP粘结长度、粘结宽度、粘贴层数下的界面粘结性能.结果表明,存在一个有效的CFRP粘结长度,并得出了该有效粘结长度范围内的粘结强度值,这与有关结果一致,说明自设的试验方法确实具有一定的可行性.

To clarify the effect of interface bond properties on the performance of carbon fiber reinforced plastic（CFRP） strengthened reinforced concrete（RC）, a new method of studying the bond performance was designed in terms of the strength grade of concrete, the CFRP bond length, the bond width and the number of bond layers. Results of the study show that there exists an effective bond length of CFRP; where the bond strength can also be derived. These results conform with other research. Thus the test method for bond performance designed by authors is proved practicable.
