“…When introducing new materials or increasing the material variety, new joining technologies can enable the combination of different materials. In the case of lightweight vehicle structures, this could encompass adhesive bonding [202] or new forms of mechanical joining [203]. In the case of structural elements, a good mechanical performance of joints enables certain use applications, but coincidently hinders separation at the end-of-life.…”

Lightweight structures are increasingly necessary to meet current engineering requirements. Weight reduction in diverse applications such as automobiles or machine tools is achieved either by using less material or by substituting material with a lighter one, which provides more functionality per unit of weight. To be an effective enabler for sustainability, lightweight structures should result in lower environmental impacts per functional unit when compared to conventional structures on a life cycle basis. However, applying new materials and manufacturing processes often leads to an increase in environmental impacts from the raw materials and production stage of the life cycle. Furthermore, end-of-life disassembly and recycling may become more difficult. In addition, the expected efficiency gains from the use of lightweight structures depend on how the overall market and technical systems respond to them. Consequently, the environmental evaluation of lightweight structures in engineering entails various methodological challenges. Organised around a life cycle engineering framework with a focus on eco-effectiveness, this paper provides a comprehensive review of lightweight structure applications and the challenges and opportunities they present in a life cycle engineering context.

“…These are mainly Carbon or Glass Fiber Reinforced Plastics (CFRPs, GFRPs) where the most common matrices are thermoset resins (such as polyester or epoxy) and thermoplastic polymers (such as polyamide or polypropylene) [14]. Composites are also widely used in combination with metals to form hybrid, multi-material and sandwich structures through the adoption of joining technologies (such as adhesive bonding [15], rivets [16] or new forms of mechanical joining [17]) to combine different materials on a part level. These types of solutions offer a great potential of mass decrease which, in turn, lead to significant improvements in terms of vehicle performance, safety and cost.…”

Design of a Lightweight Rear Crash Management System in a Sustainable Perspective

2020

The paper presents an innovative lightweight design solution for the rear crash management system of a C-class car, developed within the AffordabLe LIghtweight Automobiles AlliaNCE (ALLIANCE) EU research project. The innovation provides that the reference version of the module, based on conventional steel components, is revolutionized through the introduction of extruded 6000/7000 series aluminum alloys. The two competing alternatives are described and compared in relation to design and technological solutions, including also a sustainability analysis which assesses the entire Life Cycle (LC) of the system on the basis of a wide range of environmental indicators. The lightweight solution allows achieving a large mass reduction (almost 40%), while providing improvements in terms of strength, production efficiency and design freedom. On the other hand, the introduction of new materials and manufacturing technologies entails contrasting sustainability effects depending on impact category, thus not allowing to affirm that the novel alternative is unequivocally preferable under the environmental point of view. However, the comprehensive evaluation of all sustainability aspects through a multi-criteria decision analysis (TOPSIS method) reveals that the environmental profile of the innovative design is slightly preferable with respect to the conventional one.
