The perpose of this study is to establish the new method for evaluating the adhesive strength of thick film. It has been studied to develop new method to evaluate the adhesive strength of interface between adherent and thick film on the surface of adherent.A summary of the obtained results are as followed.(1) New peel test equipment capable of measuring peel load and peel length was designed and manufactured.(2) The peel test for FRP lining films on cement mortar surface and ceramic spray deposit films on stainless steel were carried out. The critical energy rerease rate (Gc value) were obtained by using peel load and peel length mesured during peel test. Gc values were not affected by peel length and thickness of film. Therefore it was cleared that Gc values could be used to evaluate the adhesive strength of thick film.(3) It was difficult to determine accurately the value of peel length in practical peel test. So convenienced method to calculate the critical energy rerease rate (Gc value) without measuring peel length were derived. In convenienced method, Gc value were obtained by using peel load and displacement of load point.

这项研究的持久性是建立一种评估厚膜粘附强度的新方法。已经对其进行了研究，以开发新方法，以评估粘附表面上粘附和厚膜之间界面的粘合强度。通过使用果皮负载和果皮测试中的果皮长度获得临界能量恢复速率（GC值）。 GC值不受薄膜的剥离长度和厚度的影响。因此，可以清楚地看出，GC值可用于评估厚膜的粘附强度。（3）很难准确确定果皮长度在实用的果皮测试中的值。因此，得出了未经测量果皮长度的无需计算临界能量恢复速率（GC值）的便利方法。在便利的方法中，使用果皮负载和负载点的位移获得了GC值。
