“…It is assumed that reducing the vehicle weight by 100 kg allows for fuel savings of approximately 0.6 dm 3 per 100 km. When the vehicle mass is reduced by 100 kg, the fuel consumption is reduced by about 0.4 dm 3 /100 km, and the CO 2 emission decreases by 7.5 to 12.5 g/km [11]. Aluminium alloys are corrosion resistant and have high mechanical strength.…”

The development of lightweight and durable materials for car body panels and load-bearing elements in the automotive industry results from the constant desire to reduce fuel consumption without reducing vehicle performance. The investigations mainly concern the use of these alloys in the automotive industry, which is characterised by mass production series. Increasing the share of lightweight metals in the entire structure is part of the effort to reduce fuel consumption and carbon dioxide emissions into the atmosphere. Taking into account environmental sustainability aspects, metal sheets are easier to recycle than composite materials. At the same time, the last decade has seen an increase in work related to the plastic forming of sheets made of non-ferrous metal alloys. This article provides an up-to-date systematic overview of the basic applications of metallic materials in the automotive industry. The article focuses on the four largest groups of metallic materials: steels, aluminium alloys, titanium alloys, and magnesium alloys. The work draws attention to the limitations in the development of individual material groups and potential development trends of materials used for car body panels and other structural components.

“…One way to reduce the weight is to use lightweight construction materials of high strength. These requirements are met by composite materials based on metal and polymer alloys, which are increasingly used in mechanical engineering and transport [42,43,44,45,46,47,48,49,50,51].…”

This paper presents the results of laboratory tests in which evaluation was performed regarding the effect of selected operating factors on the vibroactivity of upper gearbox housings made of three different fiber reinforced polymer composite materials with diverse layouts (cross and random) and types of reinforcing fibers: glass fiber and carbon fiber. The results of tests for composite housings were compared with those for a steel housing. The tests showed that composite housings had a weight lower by more than 60% compared to the steel housing. A multisensor measuring system consisting of vibration acceleration transducers, a directional microphone and a data acquisition card with software was used for the study. Tests of the vibroactivity of upper gear housings were carried out at different loads and rotational speeds of toothed gears. The study showed that composite housings are less sensitive to changes in the rotational speed that steel housings. The tests showed that at a higher rotational speed of the gear transmission, housings made of composite materials had a comparable or lower level of vibration. Tests and analyses of the vibroactivity of housings performed at different loads of the gear allow the conclusion that composite housings, despite a considerably lower weight than steel housings, are less sensitive to changes in the load of the gearing.

“…The demand for new and customised personal vehicles are increasing at an exponential rate with the increase in buying power of customers. Transportation is identified as the major sector contributor to the accidents and the CO2 emissions [1]. The greatest challenges faced by the automotive industry has been to provide safer vehicles with high fuel efficiency at competitive cost.…”

Automotive design with economy, safety and aesthetics have been a great challenge to design engineers. Augmenting to these factors today environment impact is an upcoming research area. The safety of the passengers during vehicle crashes can be ensured to a certain limit by using good bumpers. At the same time these automotive parts should not be massive in terms of weight contributing to the increase in total the weight of the vehicle. In this work, a bumper used for low passenger vehicle, Ambassador car is modelled by using the software CATIA V5R18. Then this model is imported into FEM package of ABAQUS 6.10 impact as well as static analysis. Again modal analysis and analysis under dynamic loading done for the same model using ANSYS Workbench 11.0. The materials used for these analyses are Aluminum B390 alloy, Chromium coated mild steel and carbon composite. During static analysis, Carbon composite shows the lowest deformation and maximum von mises stress value. After the impact analysis, the composite shows the highest stress value, lowest deformation and the lowest strain value on compared with above materials. The analysis under the dynamic loading shows this carbon composite has the maximum stress value and it having the highest strength to weight ratio and producing low deformation. From all these analysis, it can concluded that carbon composite is the best material which can use as the bumper material among all the other materials used here.
