The use of aluminium in transportation applications is predicted to double over the next 10 years. The use of extruded aluminium in structural components such as space frames is a growing area, and bending is an integral and critical process in the production of such components. The aim of this project is to develop key knowledge and technology necessary for precision bending of extruded aluminium profiles. The main outcomes will be: (i) Understanding of the relationship between extrusion conditions, microstructure and bendability of structural profiles. This will enable the optimisation of the extrusion process to ensure consistent bending behaviour. (ii) Development of the rubber-pad technology for precision bending.
