摘要
Bondal is the denomination of a vibration damping sandwich sheet, which is mainly used in automotive industry for sound and vibration damping. In this paper, the formability of this sheet was investigated by conducting different types of experiments such as uniaxial tensile, hydraulic bulge, Nakazima and T-peel tests. Furthermore, SEM analyses have been performed to assess the bonding strength of layers and possible delamination due to deformation. The obtained results include the uniaxial tensile curves of the Bondal sheet and its components, the forming limit diagram (FLD) of the Bondal sheet, bulging limit strains and bulging height at the onset of fracture, T-peel test force curves and so on.
