    摘要:

    铝合金材料的可焊性较差,焊接热影响区强度降低显著,用碳纤维布加固铝合金是一种有效的措施.为此探究了碳纤维布与铝合金间的黏结性能,完成2批共计37个碳纤维布加固铝合金双搭接节点试验,研究了碳纤维布黏结长度、宽度、层数、碳纤维布材料以及黏结构造等对黏结效果的影响.总结了碳纤维布加固铝合金双搭接节点的破坏模式和破坏机理,得到碳纤维布的应力应变分布规律,提出了双搭接节点的有效黏结长度和承载力实用计算公式.

    Abstract:

    The strength in heat affected zone of welded aluminum alloy decreases sharply. One of the effective measures is to use CFRP sheets for reinforcement. A shear experiment of 37 double lap joints of aluminum alloy reinforced with CFRP sheets, including specimens with different CFPR bond length, bond width, bond layers, single layer thickness and bond form, was conducted. Failure modes, bond mechanism between CFRP sheets and aluminum alloy, and strain distribution were studied. Besides, effective bond length and ultimate load calculation formulas of the double lap joint were proposed.
