- Abstract
The purpose of this case study is to calculate the critical condition of interfacial peeling on aluminum hybrid anti-mechanical vibration panel. An area of thin-cored resin layer with two aluminum skins is located to design a hybrid panel. The system of hybrid panel is normally used for mechanical parts, which need to dampen mechanical vibration. In this structure, a thin core plays an especially important role to dampen vibration. However, this structure has a disadvantage of delaminating and peeling with perpendicular loading from the adhesive core. At a given level of adhesion, one calculates deflection and stress state as a function of loading. To confirm that this model is directly applicable to the quantity of deflection, the geometry of three layers is designed with actual product thickness. A total of five cases of loading condition are simulated to deduce the stress distribution. The interfacial area is the main interest for this simulation which can be related with critical peeling condition. As a result, the comparison with the practical values of adhesion shows a possibility of estimation for the peeling limit of this hybrid panel system.
