Summary

The new fastening technique of elastic bonding complements the existing range of traditional fastening methods. The first use of elastic adhesives to bond components and assemblies in the manufacture of vehicles dates back to the early 1980s. The modern rail industry now depends on elastic adhesives for a whole range of fastening applications – including roof assemblies, window glass, side walls, front and rear ends, floor pans and countless smaller assemblies. The bonding of all these components to the structure helps to increase the stiffness and reduce the weight of the vehicle. By this the latest generation of trams weights up to a third less than their predecessors, this helps to reduce the life cycle cost.

Major assemblies such as the driver's cabin or complete roof elements can be pre-assembled, with their interior linings, and then bonded with elastic adhesives to the bodyshell. This method avoids the high stresses associated with welding, and the thick-layer adhesive helps to bridge large manufacturing tolerances between the components. All this helps to reduce the production costs.

The correct joint design needs to take account of the specific mechanical properties of the substrates and the adhesives used. Simply substituting an elastic adhesive for a rigid fastening will not achieve the desired result. The key to the successful use of adhesives lies in consultation between the product designer and the adhesive manufacturer, who can advise on the best way to configure assemblies and joints for elastic bonding.
