摘要
为了研究GFRP(玻璃纤维)与CFRP(碳纤维)混杂后的界面性能,采用双面剪切的试验方式,进行了G/CFRP(混杂后纤维)与混凝土剥离承载力分析、应变分析以及粘结剪应力分析。试验表明:GFRP经过CFRP混杂后,可以有效地提高界面剥离承载力。G/CFRP-混凝土界面剥离有效粘贴长度在60mm左右,GFRP-混凝土界面剥离有效粘贴长度在80mm左右。
In order to study the interracial performance between hybrid fiber and concrete, the testing method of double shear is applied, and the analyses of the stripping bearing capacity,the strain and the interfacial bonding shear stress of hybrid fiber are carried out. The experimental results show that the stripping bearing capacity of hybrid fibers is better than GFRP. The effective pasting length of interracial performance between hybrid fiber and concrete is about 60 ram, and as for GFRP, the effective pasting length is about 80mm.
