Trends in Lightweight Automotive Materials for Improving Fuel Efficiency and Reducing Carbon Emissions (original) (raw)

Article Info Depletion of fossil fuels and greenhouse gases is an essential issue in the development of the automotive industry. From the design stage, material selection becomes the most crucial factor. Therefore, this article discusses the development of lightweight automotive materials for increasing fuel efficiency and reducing carbon emissions. Material reliability is assessed by how much weight reduction can be achieved, production costs, safety and durability. Ferro materials (mild steel, High Strength Steel, and Advanced High Strength Steel), non-ferrous (aluminium and magnesium alloy), and Fiber Reinforced Plastics (FRP) have been proven to reduce the total weight of vehicles up to 12.6%. Confirmation of statistical data from the literature illustrates the possibility of using lightweight material to achieve zero CO2 emission. In addition, the 12.6% weight reduction still meets the vehicle safety factor. Abstrak Penipisan bahan bakar fosil dan gas rumah kaca adalah menjadi isu penting dalam perkembangan industri otomotif. Dari tahap disain, pemilihan material menjadi faktor terpenting dan yang pertama kali dipertimbangkan. Oleh karena itu, artikel ini membahas perkembangan material otomotif bobot ringan untuk peningkatan efisiensi bahan bakar dan pengurangan emisi karbon. Keandalan material dinilai dari seberapa besar pengurangan berat yang dapat dicapai, biaya produksi, tingkat keselamatan dan ketahanan. Material ferro (mild steel, High Strength Steel, dan Advanced High Strength Steel), non-ferro (paduan aluminium dan magnesium), dan Fiber Reinforce Plastics (FRP) terbukti dapat mengurangi berat total kendaraan hingga 12,6%. Konfirmasi pada data statistik dari literatur, memberi gambaran kemungkinan penggunaan material bobot ringan dapat mencapai zero CO2 emision. Selain itu, pengurangan berat 12,6% masih memenuhi faktor keamanan kendaraan.
