GFRP复合材料与粘土砖单剪粘结试验研究

采用玻璃纤维复合材料-粘土砖单剪试验方法,考虑GFRP粘结长度、粘结宽度、粘结树脂的类型及粘贴层数等因素,对GFRP与粘土砖之间的极限粘结荷载进行了深入研究。研究结果表明,粘结破坏有GFRP剥离破坏和GFRP断裂破坏两种形式;GFRP粘结长度、粘结宽度、粘结树脂的类型、粘贴层数及砖抗压强度等因素对极限粘结荷载有显著影响。

Experimental study on single shear strength between GFRP and clay brick

The bond strength between GFRP and clay brick is studied by experiments on a single shear test set-up with emphasis on the effects of the GFRP bond length,bond width,type of bond resin and bond layer.Following conclusions are drawn from the study: 1) there are two kinds of failure modes,namely GFRP debonding failure and GFRP rupturing failure;2) the bond length,bond width,type of bond resin,bond layer and compressive strength of clay brick have significant effects on utmost bond strength.
