“…Current solutions include designing for manufacturability, recyclability, and durability, which emphasize reducing number of parts, ease of disassembly, and increasing durability . Using fewer materials and reducing part count can also be effective, as demonstrated by the Multi Material Lightweight Vehicle (MMLV), developed by Magna International and Ford Motor Company, which achieved a 23.5% mass reduction using part consolidation and aluminum substitution . Less labor-intensive dismantling can be achieved through modifications to standard designs, and several significant policies have promoted the idea of designing for dismantling and reuse, including the European Parliament’s Directive 2000/53/EC, which raised the required reuse of vehicle materials to 85%. , Development of new aluminum alloys that better match metal streams and do not require additional processing would help to address some of the current limitations with aluminum end-of-life …”

A large portion of life cycle transportation impacts occur during vehicle operation, and key improvement strategies include increasing powertrain efficiency, vehicle electrification, and lightweighting vehicles by reducing their mass. The potential energy benefits of vehicle lightweighting are large, given that 29.5 EJ was used in all modes of U.S. transportation in 2016, and roughly half of the energy spent in wheeled transportation and the majority of energy spent in aircraft is used to move vehicle mass. We collect and review previous work on lightweighting, identify key parameters affecting vehicle environmental performance (e.g., vehicle mode, fuel type, material type, and recyclability), and propose a set of 10 principles, with examples, to guide environmental improvement of vehicle systems through lightweighting. These principles, based on a life cycle perspective and taken as a set, allow a wide range of stakeholders (designers, policy-makers, and vehicle manufacturers and their material and component suppliers) to evaluate the trade-offs inherent in these complex systems. This set of principles can be used to evaluate trade-offs between impact categories and to help avoid shifting of burdens to other life cycle phases in the process of improving use-phase environmental performance.

“…10 The project used steel self-piercing rivets (SPRs), which is a type of rivet that doesn't require a predrilled hole, as the primary joining technique with an epoxy structural adhesive applied for added strength and isolation to prevent galvanic corrosion. 11 Subsequently, a number of vehicles using lightweight materials and requiring dissimilar material joining have gone into production, including the 2013 BMW i3, 2015 Ford F-150, 2016 Cadillac CT6, and the 2017 Chrysler Pacifica. A key challenge in producing multimaterial structures is determining the best method to join the dissimilar material components.…”

“…4 It allows the design to satisfy high requirements in terms of comfort and safety while simultaneously reducing the overall weight of the vehicle. In 5 Conklin integrated high strength steel and aluminium components in the body in white of a midsized high volume production vehicle. A mass reduction of 27% was achieved to demonstrate the potential of lightweight design.…”

Owing to the implementation of multi-material construction methods in modern lightweight construction and the associated use of adhesive bonding technology, thermally induced relative displacements of the joining partners occur during the curing process. The resulting extremely complex thermo-chemo-mechanical stresses can influence the properties of the adhesive layers and reduce the load-bearing capacity. In this study, experiments are conducted to examine the influence of process-related thermal relative displacements on the mechanical properties of adhesives. The results show an anisotropy of the mechanical properties of the pre-deformed adhesive layers, depending on the magnitude and direction of the relative displacement.
