A case of internal observation using X-ray CT, aiming to discover the vibration damping mechanism
Press Releases | June 23, 2022
Towards the development of next-generation functional rubber materials
The research team formed by the Department of Mechanical Engineering of Toyohashi University of Technology, Professor Asahiro Nagatani of Hyogo Prefectural Institute of Technology (currently the National Institute of Advanced Industrial Science and Technology), and Professors Nobuyoshi Tsujiuchi and Akihito Ito of the Science and Engineering Department of Doshisha University found out by using the synchrotron radiation X-ray computed tomography (CT) that the improved vibration damping of rubber materials associated with the compounding of fine particles is related to the deformation behavior of the microstructure. They discovered that performing deformation evaluations at the macroscale (in the order of mm) and at the microscale (space resolution when using the X-ray CT: 500nm) at the same time can obtain the internal nonuniform deformation of a material in the scale of several dozens mm. The results of the research were released online on May 9, 2022 in Polymer Testing.
