Abstract
Interfacial bond strength is one of the vital mechanical properties of adhesives. The cross-bonded method, which is widely used to measure the interfacial tensile and shear bond strength simultaneously, has attracted extensive attention. An improved cross-bonded method is presented in this study in order to promote the accuracy and reliability of the testing results. The ergo 9900 glue, E-7 glue, AB glue and 502 glue were measured in this study. Compared with the original method, the results of the improved cross-bonded method show that: (i) the coefficient of variation of the interfacial bond strength decreased significantly; (ii) the interfacial shear bond strength of the adhesives is closer to its true value.
