Multiscale Composite Materials: Fabrication and Characterization



报告题目:Multiscale Composite Materials: Fabrication and Characterization

报告人:Prof. Liyong Tong (University of Sydney)






This talk presents our recent research outcomes on grafting of carbon nanotubes (CNT) on carbon fibres (CF) and the associated multiscale functional composites. The talk covers the following: (a) a brief overview of on fibre reinforced composites and existing carbon fibre surface modification methods; (b) a low temperature chemical grafting method for connecting nano entities, such as CNTs and graphene, and carbon fibre surface via chemical bonding; (c) experimental evidences demonstrating covalent bonding between CNT and CF; and (d) introduction of a novel twin fibre single lap test method and assessment of mechanical behaviours, including interfacial strength, in multiscale functional composites; and (e) measurement of super capacitance property.



Dr Liyong Tong received his PhD in 1988 and became a full professor in the School of Aerospace, Mechanical and Mechatronic Engineering at the University of Sydney in 2004. His primary research interests consist of analysis, design and manufacturing of multiscale 3D composite and smart materials and structures with practical applications. His research was funded by government agencies and industries, e.g. ARC, DSTO, AOARD/AFOSR, CRC-ACS, Boeing and Airbus etc. He published over 250 journal articles and has been active in collaborating with colleagues globally.
