To reduce the environmental impact of automobiles, it is important to improve their fuel efficiency, and vehicle weight reduction is one way of achieving this. In recent years, the adoption of CASE has become a key for automobile development. As a result, the weight of automobiles has been increasing due to the increase in the number of ECU units, the number of sensors, and the weight of batteries. Thus weight reduction is essential for CASE. Furthermore, to achieve such reductions, a combination of technologies is required. Various technologies are being developed, including the use of composite materials such as GFRP, CFRP, CFRTP, and CNF reinforced plastics, press working technology for new metallic materials such as high-tensile strength steel and aluminum alloys, analysis technology to improve design accuracy, multi-material technology, and 3D printing technology, which is expected to be used for future automotive structure development.The SHIMADZU Automotive Technology Webinars for Weight Reduction provide support for achieving weight reduction by introducing detailed information about the latest technologies for each of the technical themes below and the evaluation technologies they require.
