Mechanical properties of various fiber reinforced composites.
Mechanical Properties and its scatter of carbon fiber reinforced composite: Mechanical properties of unidirectional carbon fiber reinforced composites were examined. Important parameters are toughness of matrix and interfacial properties. Based on this consideration, a new method which increases strength and decreases the scatter is presented. Braided composites: Braiding structure is one of the textile technologies. In this presentation effectiveness of utilization of braided structure as reinforcement for composites will be explained. The most important point is continuity of reinforcing fibers through composite structure. Crushing performance of composite materials: Crushing performance of materials can be evaluated by using specific energy absorption values which is called Es. Composites has higher Es value than steel and Al. Various fracture behaviors are involved during crushing fracture process. The important point is fiber fracture, in other words many fiber fracture can generate high Es in composites.
Bio: Dr. Hiroyuki Hamada has been Professor of Advanced Fibro-Science, Kyoto Institute of Technology since 1998. He is also Director of Future-Applied Conventional Technology Center, Kyoto Institute of Technology founded in 2005. He has an established record of research in the area of polymeric materials, textile composites, especially the composite materials reinforced with braided fabric. He is a reviewer of many international journals and has acted as chair and co-chair in several professional organizations. Now he is the director of Future-Applied Conventinal Technology Center from April of 2005 and the director of Advanced Fibro science in Kyoto Institute of Technology from April of 2006. Prof. Hiroyuki Hamada was born in Osaka of Japan in 1955. He received his doctoral degree from the Department of Mechanical Engineering, Doshisya University, Japan in 1985. After that he worked at Osaka Municipal Technical Research Institute for 4 years and then joined the Division of Advanced Fibro science in Kyoto Institute of Technology as an assistant professor firstly. He research interests were concentrated on composites and the related technology and engineering. During the following 12 years' researches, he got 8 awards from various domestic or international conferences and the professor title in 1998. He has been the executive director and council member of more than 40 academic organizations and the editor of 12 academic journals. From 2005, he was selected to be the director of Future-Applied Conventional Technology Center in Kyoto Institute of Technology. And his research field was extended to tradition craft technologies. He believes that the excellent skills and wisdom which are inhered in tradition craft combined with modern technology can help people to make new products for future.
