| 摘 要： | 利用三点弯研究了水泥砂浆外贴碳纤维和芳纶纤维片材后的抗弯性能,并对2种纤维进行表面处理,探讨纤维的表面处理对FRP水泥砂浆体系抗弯性能的影响。结果表明,用等离子体分别对碳纤维和芳纶纤维进行表面处理,CFRP和AFRP水泥砂浆的最大断裂载荷都能显著提高,而且构件在受弯过程中没有发生剥离破坏,FRP被拉断,纤维高强的特点得到充分发挥。

| Abstract: | The flexural properties of cement externally bonded carbon fiber sheet and aramid fiber sheet respectively were investigated by the three-point bending test.The surfaces of these two fibers were modification and the influence of surface modification of fibers on the flexural properties of FRP-cement systems was also discussed.The results show that the maximum load of CFRP-cement and AFRP-cement increases obviously after carbon and aramid fiber sheets were modified by plasma.Furthermore,peeling-off doesn't happen when the specimens were bended.The FRP is tensile fracture,which shows that high strength of the fibers works. |
