报告题目：Stitch up the Interface: Recent Advances on Manufacturing of Hierarchical, Multifuncational Structural Composites
报告人：阿拉巴马大学 王家来教授
报告摘要：This study explores a novel nanoengineering technique, Poptube technology, and to use this method to manufacture hierarchical, multifunctional structure composites with superior mechanical performance and durability. The PopTube technology is a novel approach to fast grown CNTs on reinforcing fibers in large volume in ambient environment with no need of any inert gas protection, and additional feed stock gases, typically required in chemical vapor deposition (CVD) approach. Experimental studies have revealed that the interlaminar fracture toughness of composite laminates can be significantly enhanced by this technology. Single fiber testing shows that damage to the fibers/fabrics caused by PopTube Technology is insignificant. Compared with existing CVD method, PopTube technology enjoys many advantages. It requires very simple equipment, can be easily scaled up for large-scale manufacture, and is highly energy-efficient and cost-effective. PopTube Technology has great potential to enable large-scale application of CNTs in nest generation multiscale, multifunctional structural composites.
