“…Proposed solutions demonstrate an interesting lightweighting potential coupled with structural performances. Costs due to lightweighting and TAKT time are in line with the request for medium production volumes (≥30,000 units/year) ( Table 3) (Cischino et al, 2017). Weight and costs lower respect to baseline for 30,000 units/year; b any baseline ref.…”

Based on Pininfarina Nido EV concept, EVolution aims to reduce the vehicle weight through new materials and process technologies, focused on five demonstrators: underbody, front crossbeam, mechanical subframe, shotgun system and door. This paper refers to body structure design strategies using new composite, Al materials and enabled technologies, focusing in particular on demonstrators design and manufacturing. The new front crossbeam geometry of the front shell is adapted starting from the Nanotough design, while the rear shell is specific for EVolution. The subframe demonstrator is redesigned to fulfil mechanical requirements of the part and manufacturing feasibility either. The EVolution door concept consists of two semistructural Evolution FP7 funded project: body structure design strategies 253 composite skins including a structural Al frame. The underbody is conceived through an integrated approach, optimising each element for its function. The shotgun component is designed to link parts obtained with different manufacturing technologies and several aluminium alloys in one single component: the structural node demonstrator.

“…Energy consumption and CO 2 emissions are directly affected by the low weight of the transportation body. A multi-material body is crucial for reducing CO 2 emissions as it allows for a very low weight and decreased production costs [1]. To reach this goal, it is possible to use new materials, new combinations of bimetallic joints, or suitable advanced methods of material joining.…”

This study aims to investigate a friction stir welded joint between steel and aluminum alloy. FSW is nowadays one of the most interesting joining techniques due to the possibility of connecting materials and thicknesses that are difficult or impossible to weld with traditional techniques. The main advantage is that materials are not affected by thermal cycle problems during solidification and cooling, and the absence of fumes and pollution during the process favors the quality of the welded joint. The life of metal joints could be greatly reduced in a corrosive environment since the less noble material will tend to increase its corrosion rate, while the nobler one will reduce its electrochemical dissolution. Accelerated aging tests (i.e., salt fog test) are used to estimate the lifetime of metal joints in highly aggressive environments. The aim of the present work is to evaluate the durability at a long aging time in the salt spray test (according to ASTM B117) of carbon steel/aluminum alloy joints, obtained by FSW. In this first part, mechanical test results are reported. A deep metallographic and chemical investigation is going to be reported in part two. The current research work investigates the welding direction and residence time in the salt spray chamber. The breakage of all tested samples, evaluated after the tensile tests were carried out, always occurs at the interface of the joint, regardless of the change of direction of the weld on the advancing or retreating side. The welding direction influences the breakage of the joint only before the aging treatment. Specifically, specimens produced in advance are characterized by increased joint strength. On the other hand, the factor that influences the performance of the joints is the exposure time where, starting from the first point of aging, i.e., after two months, there is a decrease in the maximum load of 40%, and the effect of corrosion leads to a significant deterioration of the weld which remains almost similar until the last point of aging.

“…The low weight of the vehicle body has a direct effect on energy consumption and CO 2 emissions. The key in reducing CO 2 emissions is a multimaterial body, which enables achieving an extremely low weight and reduced production costs (Cischino et al, 2017). This can be achieved by using new materials, new combinations of bimetallic joints, or by using suitable advanced methods of materials joining.…”

This scientific article deals with cyclic corrosion testing of bimetallic joints in order to describe the influence of different surface treatment as a protection against galvanic corrosion on bimetallic materials. Multi-material body parts joined with advanced manufacturing technologies are used to achieve the required car properties. Metallic materials have different values of electronegativity and joining increases the risk of corrosion. Different types of coatings are used to prevent galvanic corrosion, but each increases investments and costs. Galvanic corrosion affects the lifecycle of the car. Cyclic corrosion testing provides replicable results to estimate the range of corrosion in a real environment. Test specimens from different materials were riveted and treated with various surface treatments. The method and design of samples preparation is unique and reflects the reality more than current methods. It has not yet been published in any literature. The corrosion test was performed for 6 weeks. Samples were subjected to a salt mist with temperatures of 25 °C and 50 °C, wetting and drying phases. The samples were evaluated according to the standard EN ISO 4628-1:2016. Microscopic and energy-dispersive analysis were performed. Tests have shown considerable galvanic corrosion on uncoated samples. On the samples with ecoated surface galvanic corrosion was not recorded.
