Light-Join

Joining technologies to enable implementation of lightweight structures in the automotive industry.

Partners: Jaguar Land Rover, Far-UK, Stadco, Nissan Motor Manufacturing UK, Scott Bader Company, Autotech Engineering R&D UK, Granta Design, TWI, University of Warwick - WMG

The automotive industry faces major challenges to meet targets for emissions, efficiency, performance and cost. The light-weighting of parts using composites enables all of these to be addressed, except for cost. A key driver of the cost of composites is the limited ability and capacity of the joining technology available. In project Light-Join, Jaguar Land Rover (JLR), Nissan and their Tier 1 suppliers aim to develop a number of solutions that will enable cost-effective integration of high-performance composite components into volume car production. Light-Join aims to enable replacement of specific metal vehicle components with composites, specifically focussed on developing rapid joining solutions, raising the manufacturing maturity to produce a small scale demonstrator component (MRL5) and assessing the potential for scale-up to MRL9A. This project will develop a solution leading to 30% weight reduction for all-aluminium construction (for JLR) and 60% compared to an all-steel construction (for Nissan). This approach will have industry-wide applicability, allowing a lower risk introduction of lightweight composite components to the mass market.
