Carbon nanofiber modified FRP rib and preparation method and application thereof
The invention belongs to the field of engineering materials, and particularly relates to a carbon nanofiber modified FRP rib and a preparation method and application thereof. The method comprising the following steps: dispersing carbon nanofibers into a resin matrix to obtain modified resin, and compounding the modified resin with a non-conductive continuous fiber bundle to form the modified FPR rib. The modified FPR rib has a strain self-monitoring function, the purpose of mastering the strain of the modified FPR rib in real time is achieved by measuring the resistance of the modified FPR rib in use, and meanwhile, the modified FPR rib has the advantages of being free of damage to host materials, good in stability, flexible in distance measurement selection, free of special collecting and analyzing instruments, visual in result and the like. The invention also provides a preparation method and an application of the carbon nanofiber modified FRP rib. The resistance of the modified FRP rib in the concrete is monitored, and the purpose of monitoring the stress state of the FRP rib in the concrete is achieved by utilizing the force resistance effect of the modified FRP rib.
本发明属于工程材料领域，尤其是涉及一种碳纳米纤维改性FRP筋、其制备方法及应用。包括碳纳米纤维分散到树脂基体得到改性树脂，所述改性树脂与不导电连续纤维束复合，形成所述改性FPR筋。本发明改性FPR筋具备应变自监测功能，使用时通过测量自身电阻来实现实时把握改性FRP筋应变的目的，同时具备对宿主材料无损、稳定性好、测距选取灵活、无需特殊的采集和分析仪器、结果直观等优点；本发明还提供一种其制备方法及应用，对混凝土内改性FRP筋的电阻开展监测，利用改性FRP筋的力阻效应，达到监测混凝土内FRP筋受力状态的目的。
