[email protected] warwick.ac.uk/lib-publications Richard Woodward EngD Portfolio Innovation Report Towards high-volume, primary bonded, lightweight automotive structures. by Richard John Roy Woodward Innovation Report Submitted to the University of Warwick in partial fulfilment of the degree of Doctor15 February of Engineering 2016 Wednesday 31st October 2018 Richard Woodward EngD Portfolio Innovation Report Abstract Increasing pressures upon high-volume automotive manufacturers has led to the requirement for lightweight body structures. These increasingly require the introduction of lightweight materials, such as fibre reinforced polymer composites. As a result, effective joining technologies are a key automotive industry requirement to enable the introduction of optimal, lightweight material combinations to automotive body structures. Following an extensive literature review, adhesive bonding techniques were identified as a potentially suitable joining solution. However, two key barriers to the adoption of adhesive only, primary bonded, structural joints within the high-volume automotive industry were identified. These were the requirement for optimal surface treatment methods for composites, applied prior to adhesive bonding and a technique to achieve rapid joint handling strength during manufacture.
