Abstract
The manufacturing of rubber-to-metal bonded parts is a complex problem. Several very different parameters must be correctly brought into agreement with each other and defects can easily occur. The preparation of the metal surface, a suitable bonding system, the right rubber compound and the entire production process are among the important parameters. The present work deals with the influence of the surface roughness of the metal component, the mould cavity pressure and the ageing of the rubber compound during storage. A significant correlation was shown between the 3D roughness Sv and the strength of the bond between rubber and metal. In addition, the strength also increases with mould cavity pressure. This correlation can be expressed by a saturation function. Furthermore, a number of indispensable compound characteristics were clarified.
