Bus structures made of adhesive bonded aluminium extrusions

A method of producing bus structures has been developed using adhesive bonded aluminium extrusions for the side roof, floor rails and pillars. Various adhesive bonded joints were tested for strength and durability. Separate analytical exercises were done to study the stiffness, strength and energy absorption properties of the components and complete structure. All body components and 2 complete bays have been produced and are undergoing validation in terms of stiffness, durability and crashworthiness under rollover conditions. In order to assess the new technology under more realistic service conditions, the consortium is seeking further development support to manufacture 2 complete prototype vehicles. One prototype would be subjected to laboratory tests within the elastic range and finally to a rollover test. The other one would be used for a longer-term assessment in service.
