IMPACT PERFORMANCE OF A STRUCTURAL BONDING TAPE

摘要

The objective of this work is to investigate the behavior of a viscoelastic adhesive, Structural Bonding Tape 9245 (SBT), under impact loading using the single lap joint configuration. The material has already been tested for the investigation of its mechanical and dynamic behaviour in quasi-static and dynamic tests. Statically, SBT showed a high strain to failure with a reasonable stress and high damping. These features of the adhesive under impact test enlighten the contribution of such materials to the crash worthiness of the structures. Results show that the joints strength increases considerably under the impact loading compared to those under quasi-static loading and that there are a relationship between the joint performance and the loading speeds.
