摘要:
针对碳纤维增强复合材料（CFRP）加固结构构件常发生界面过早剥离破坏的问题，进行了4个粘贴CFRP布试件的冲击试验和2个静力对比试验，主要研究CFRP与钢材界面动态粘结性能。从界面的破坏形态、CFRP应变分布以及荷载滑移曲线等方面，对冲击荷载和静力荷载下CFRP与钢材界面动态粘结性能进行了对比分析。在试验的基础上，提出了基于梁式试验法的局部粘结应力滑移本构关系计算方法。结果表明：冲击荷载下CFRP应变分布曲线与静力荷载下相比更加陡峭；界面极限动态承载力有所提高。
Abstract:
According to the problem that carbon fiber reinforced polymers (CFRP) prematurely debond from the strengthened structure members, four specimens bonded with CFRP sheet under impact load and two specimens under static load were tested. The dynamic bond behavior of CFRP sheet-steel interface was mainly investigated. The failure modes, the strain distribution of CFRP as well as loadslip curves under impact load were compared with those of static load to study dynamic interfacial bond behavior. Based on the tests, calculation method of bond-slip constitutive relations based on beam test method was proposed. The results show that the strain distribution gradient of CFRP sheet under impact load is sharper than those under static load, and interfacial ultimate bond strength is increased.
