| 摘 要： | 通过单丝拔出微观力学试验研究了纤维表面处理对碳纤维水泥基复合材料功能响应的影响.未经表面处理的碳纤维表面惰性大,与基体的结合强度低,容易脱黏,界面韧性和稳定性差,以脱黏破坏为主的界面结构变化,使试样电阻上升较快；碳纤维经过表面处理后,其与基体的结合强度提高,纤维拔出过程中试样电阻的变化平缓,显示了随着界面黏结强度及界面...

| Abstract: | Single fiber testing was carried out to study the effect of fiber surface treatment on mechano-electric properties between carbon fiber and cement.As-received carbon fiber is deficient in the chemical groups on the surface.The surface of the fiber is inactive.The Varder Waal force between fiber and cement matrix is a dominant force.The bonding strength is low and interfacial debonding is easy.The reliability and repeatability of the sensing ability is low.Surface treatment of the carbon fiber improves both ... |
