为了防止CFRP层合板/钢板节点的脱粘破坏，本研究尝试采用g形夹紧锚固体系来消除节点末端剥离应力导致界面脱粘。通过双带拉伸试验，获得了CFRP/钢界面有端部锚固和无端部锚固的粘结特性，验证了端部锚固的有效性。通过对薄弱点进行锚固，可以提高复合板的粘结强度。然而，为了完全防止复合材料的剥离，还需要进一步研究一种更先进的抗强剪应力锚固体系。
In order to prevent the debonding failure of CFRP laminate/steel plate joints, this study attempted to use a G-shaped clamp anchorage system to eliminate the peeling stress at the end of joints which causes the debonding of interfaces. Bond characteristics of CFRP/steel interface with and without end anchorage were obtained by conducting double strap tensile tests, and the effectiveness of end anchorage was verified as well. By anchoring on the weak points, the bond strength of the composite plates can be increased. However, for completely preventing debonding of the composites, a more advanced anchorage system which could against the intensive shear stress still needs further investigation.
