Yoshida Lab. focuses on the materials science and engineering in the field of transportation and energy plant. We utilize our strong connection with several major companies in automotive, aerospace, train, and power electronic module industries to develop less-defect and high-reliability future generation manufacturing process based on both numerical simulation and detailed experimental validation.

In a national industry-university collaborative spacecraft development project, we exploited the state-of-the-art 3D printing technology to develop an engine thruster that is used to control the attitude of the supply-transfer vehicle. The successfully developed thruster has been put to real application in the unmanned “Kounotori” spacecraft-series. In addition, collaborative research and development of high-strength aluminium alloy for aircraft and spacecraft structure are also conducted with the related industries.
In the field of automobile such as two/four-wheel drive, truck, and construction machinery, we are working closely with government and large national automobile industries on material research and its production development that associate to the engine and power train (transmission, suspension etc.). Additionally, on aiming to reduce the weight of vehicle, we also participates in a collaborative industry-university-government project. We are actively participating in several large national projects, and in recent years, our research activity focuses on 3D printing technology for the development of engine parts in automobile. Last but not least, we are also engaged in a national project with collaboration of related industries and other universities on developing the production technology of SiC-based power electronics module?which is the core technology in next-generation EV, HEV, and railroad vehicle.
