Abstract: Various attachment methods are employed for automotive exterior components. Among these, acrylic foam tape (AFT) has gained widespread application due to its superior stress distribution capabilities, excellent vibration damping and noise reduction properties, outstanding sealing performance, and high assembly efficiency. However, in practical engineering scenarios, AFT is susceptible to adhesion failure, which directly compromises the overall reliability of exterior assemblies. This paper provides an in-depth investigation into the critical factors influencing bonding performance, including application temperature, substrate surface finish, wet-out pressure, material selection (tape and primer), and the geometric compatibility between the component and its mating surface. Furthermore, it delineates essential design criteria for AFT integration, such as locating pin dimensions, edge clearance, release liner tab configurations, support rib design, and bonding area requirements. By synthesizing these influencing factors and design parameters, this study offers technical guidance for optimizing the bonding reliability of acrylic foam tapes in automotive exterior applications.
