Abstract
In this study, the adhesion strength for different frame materials of handheld products was investigated. To characterize the adhesive strength, a simple model of a cellphone that consists of a glass window attached to body frame using double-sided tape was designed and fabricated. The adhesion strength with different pull out speeds and aging times was measured using a conventional pull out testing method. To investigate the detailed delamination process of the adhesive layer, the digital image correlation technique was applied. Moreover, in recent years, the trend of using metal for a body frame of a cellphone has gradually increased due to the fashion of metal frames. Therefore, two materials for body frames were considered for testing in this study: Aluminum was the representative metal and polycarbonate was the representative conventional material. The results showed that the strain at the interface between the adhesive layer and body frame is higher than that at the interface between adhesive layer and glass window for both cases of aluminum and polycarbonate frames. Moreover, the fracture energy in the aluminum body frame is higher than that in the polycarbonate body frame. In order to validate the experimental results, the cohesive elements in ABAQUS™ were used for the modeling bonding layer. The results showed a good agreement between simulation and experiment.
