摘要:
通过63块烧结普通砖与碳纤维布(CFRP)、玻璃纤维布(GFRP)的单面剪切试验,分析纤维增强复合材料(FRP)与烧结普通砖粘结破坏的全过程及破坏特征.研究普通烧结砖的抗压强度、FRP种类、FRP粘结长度、粘结树脂、FRP粘贴层数等对极限粘结荷载的影响.结果表明,极限粘结荷载与FRP粘结长度有关,当粘结长度超过一定长度后,极限粘强度增加缓慢或不再增加.烧结普通砖强度对极限粘结荷载有一定影响,极限粘结荷载随着烧结普通砖抗压强度的增大而增大; 当砖的抗压强度超过27 MPa时,极限粘结荷载增大幅度变小.粘结树脂的种类对极限粘结荷载有一定的影响,特别是底层树脂对极限粘结荷载有一定的提高作用.从试验结果来看,采用"小西"树脂试件的极限粘结荷载大于采用"Lica"树脂试件的极限粘结荷载.FRP的种类影响着极限粘结荷载,CFRP与烧结普通砖的极限粘结荷载高于GFRP与烧结普通砖的极限粘结荷载.
Abstract:
By carrying out single-side shear bonding experiments between 63 pieces of fired common brick and fiber reinforced polymers(FRP),including carbon fiber reinforced polymers(CFRP) and grass fiber reinforced polymers(GFRP),the whole course of the shear bonding failure and failure characteristic between FRP and brick are analyzed.The influence of several factors on the ultimate bond strength is studied,such as compressive strength of fired common brick,type of FRP,bonding length of FRP,bonding epoxy adhesives and the number of FRP layers.Some conclusions are obtained: the ultimate bonding load increases slowly or ceases to increase when the bonding length of FRP exceeds the certain value; the ultimate bonding load increases as increasing the compressive strength of brick,the increased value slows down when the compressive strength of brick is larger than 27 MPa; the influence of type of epoxy adhesives,especially,the epoxy adhesive at bottom and the type of FRP on the ultimate bond strength is presented.The ultimate bonding load of specimen with "Xiaoxi" epoxy adhesive is larger than that of specimen with "Lica" epoxy adhesive,and the ultimate bonding load between the brick and CFRP is larger than that between the brick and GFRP.
