Abstract
As for the protection mat used for landfills, the nonwoven fabric which generally laminated fiber is used. A delamination in this laminating structure is reported as one of the causes of the damage of the protection mat. However, the general test method to evaluate detachment strength of the protection mat is not suggested. Therefore we examined a test method to evaluate detachment strength of the protection mat. As a result, we confirmed that we might evaluate detachment strength by the shear detachment examination that used a loop fastener and adhesive tape. The test also confirmed the relationship between fiber entanglement and detachment strength, the difference in detachment strength depending on the type of protection mat, and the difference in detachment strength due to the tensile member used for the test. We report an examination and the result that I went for to confirm detachment strength in this article.
