报告内容简介:


Fiber-metal laminates (FMLs) have attracted much attention because of their successful applications in A380 and Boeing 787 with excellent combined properties from both metals and fiber reinforced plastics. However, to seamlessly integrate these two materials together is a challenge for long-term service. In this talk, Dr Yang will introduce his research on the design and development of two types of FML structures: carbon fiber reinforced plastic (CFRP) tubular structure with Ti alloy as liner pipe using innovative filament winding approach, and impact resistant FML flat structure using Vacuum-Assisted Resin Transfer Molding (VARTM) method. In these hybrid systems, interfacial issues play a key role for final failure, which are tackled at different levels (i.e. at fiber-matrix, inter-lamina, and metal-composite interfaces) as well as their performances under long-term hygrothermal conditions, which is of great importance. Easy-to-apply surface treatment methods on fiber and metal have been developed to effectively improve the structural performances of these composites systems. The results provide a practical solution to design novel FML and address the interfacial problems of these hybrid composites for aerospace and other industrial applications.

Dr Jinglei Yang is currently an Associate Professor of the Department of Mechanical and Aerospace Engineering at the Hong Kong University of Science and Technology (HKUST). Prior to joining HKUST, he was an Assistant Professor at Nanyang Technological University (NTU) and a Post-doctoral Research Associate at University of Illinois at Urbana-Champaign (UIUC). He obtained his Bachelor and Master degrees from University of Science and Technology of China in 1999 and 2002, respectively, and Ph.D. degree from the Institute for Composite Materials at Technical University of Kaiserslautern, Germany in 2006. He received Wilfried Ensinger Award supported by the Scientific Alliance of the University Professors of Polymer Technology (WAK) Germany for his excellent PhD dissertation work. His research interests include multifunctional composites/structures/coatings and mechanics. He has held a number of grants as Principle Investigator with total support of equivalent CNY22 million including governmental and industrial projects. He has done significant research and innovation work in his areas and filed a number of international patents and published more than 80 refereed papers (with citation of >2000 and H-index of 21) in the high impact journals. He often gave Keynote and invited talks in the important international conferences and acted as board member and peer reviewer by invitation for a number of scientific journal.
