AIST Consortium: Building industry-academia-government collaboration using the Technological Consortium for Adhesion and Bonding (T-CAB)

12:35-13:15

Characterization of adhesive dissimilar joint properties and analysis of the joint mechanism

13:20-13:50

【Profile】

Shin Horiuchi is Chief Senior Researcher of Laboratory for Adhesion and Interfacial Phenomena in National Institute of Advanced Industrial Science and Technology (AIST), Tsukuba, Japan.
He received his Ph. D. (1997) in organic and polymer materials from Tokyo Institute of Technology. His research is currently focused on adhesion and interfacial phenomena investigated by electron microscopy.

【Abstract】

In order to clarify the metal substrate surface structure-adhesive bonding performance relationship in dissimilar bonding of CFRP and metal, nano structure of the metal surface is produced in a controlled manner and the toughness of the bonding interface between CFRTP and aluminum is evaluated by double cantilever beam (DCB) test. Furthermore, we study the bonding mechanism by electron microscopy combined with simulation.

Biodegradation of Biodegradable Plastics in Seawater

13:55-14:25

【Abstract】

Plastic waste pollution in the oceans is a serious issue. Biodegradable polymers are expected to be alternative materials to solve the issue. However, reports of biodegradation in the sea are not so much. In the lecture, marine biodegradation of typical plastics, influence of environmental stress on biodegradation, experimental procedures will be introduced.

Multi-material softwood and its application to parts for automobile

14:30-15:00

【Abstract】

Japan is one of the world's leading forest powers, with two-thirds of the country covered with forests and rich in wood resources, but it is also one of the world's leading wood importers. Although the wood self-sufficiency rate has been increasing in recent years, it is still around 30%. As a manufacturer of wooden furniture and interior parts of an automobile, we wanted to increase demand for Japanese ceder in various fields for the devastation of forests, the depopulation of mountain villages, and the regional vitalization.
In this lecture, we will introduce function addition technology and performance improvement technology as a method of utilizing Japanese cedar, a soft conifer that is endemic species to Japan. Furthermore, we will introduce potential for productization of parts for automobile and other fields that related environmental measures and efforts to SDGs, by multi-material technology for bonding cedar wood to dissimilar materials (aluminum and PC / ABS).
