Outline of Final Research Achievements

The smart non-destructive test method to evaluation the adhesion performance of sealed joint on site was proposed by pushing jig on the surface of sealant. The deformation displacement and compression of sealant force at testing were measured, and the standard tensile testing method was compared with our test and the correlation between both results was analyzed. As a result, the non-destructive method for sealed joint have a good relationship with the standard tensile test, and it was concluded that this test method is applicable to the adhesion performance test.
