Environmental impact Reducing environmental impact is an ongoing theme in the evolution of EVs. Hexagon’s Manufac- turing Intelligence division and Sumika Polymer Compounds Europe (SPC Europe) have teamed up to digitise the performance of the latter’s automotive-grade PP compounds, enabling engineers to design components that are more recyclable and offer a lower carbon footprint. Plastics can contribute up to 20% of the total weight of a car and their application is escalating with the continuing replacement of metals. The shift to e-mobility has increased the need for component lightweighting to maximise energy efficiency and mitigate the weight of battery packs, according to the companies, but their environmen- tal performance must be taken into account. “Limited material behaviour data is a barrier to sustainable e-mobility innovations because automotive engineering teams have not been able to put new materials through the rigorous virtual durability and safety tests required for automotive endorsement,” says Guillaume Boisot, Head of the Materials Centre of Excellence at Hexagon. “Our multiscale material modelling technology acceler-
ates the adoption of SPC Europe’s recycled materials by making it possible for product development teams to accurately simulate a component and subject it to established automo- tive engineering tests and validation.” Weight reduction and easier recycling are two factors also accelerating the use of EMI shielding plastics versus metal or mixed metal/plastics solutions.
