采用福克仪对在塑料与传感器之间联接系统中产生的谐振特征曲线(△f)进行了实验和理论研究。使用的材料是纤维增强塑料(FRP),塑料/金属叠层板以及带有人工缺陷的纤维增强塑料。把上述材料的谐振特征曲线△f,同那些无缺陷层板的△f 进行了比较;通过疲劳试验,把有人工缺陷的纤维增强塑料(FRP)的谐振特征曲线△f 同那些无分层的纤维增强塑料进行了比较;实验 The Fock instrument was used to experimentally and theoretically study the resonant characteristic curve (△ f) produced in the coupling system between plastic and sensor. The materials used are fiber reinforced plastic (FRP), plastic / metal laminate and fiber reinforced plastic with artificial defects. The resonant characteristic curve Δf of the above materials was compared with those of the flawless laminates. The fatigue characteristics of the FRP with artificial defects, Δf, were compared with those without delamination Fiber reinforced plastics were compared; experiment
