Carbon fiber-reinforced plastic (CFRP) based composite riser integrated with titanium liner (namely CFRP-Ti composite riser) is a promising choice for deep-water oil exploration and production to replace conventional metal risers due to its various advantages including lightweight, high specific strength and stiffness, and outstanding corrosion resistance, etc. In achieving optimal performance of this hybrid composite system, interfaces in the composite system play a critical role, which include fiber-matrix interface, interlaminar interface, and metal-composite interface (MCI). Therefore, good tuning of these interfaces determines overall performance of the hybrid composite system. To improve the interfacial properties of the CFRP-Ti composites, two different strategies have been adopted in this work: i) modification of the interfaces in CFRPs and ii) tuning of the MCI via surface treatment of titanium alloy. Multiwalled carbon nanotubes (MWCNTs) are incorporated into silane coating and applied onto carbon fiber surface to enhance the interfacial bonding in CFRPs. The results of microbond tests show that the interfacial shear strength (IFSS) of prepared multi-scale phase reinforced composite (MPRC) can be significantly increased in comparison with that of common composite. It is observed that densification of CNTs forest within the interphase between carbon fiber and matrix during forming of nanocomposite coating can lead to a high volume fraction of CNTs within the interphase and augment effects of interface-interlocking, which makes the coating-modification method a more efficient way than traditional matrix-tuning method for improving interfacial bonding. Long-term interfacial performance of the prepared hybrid composite in III Acknowledgement I would like to express my sincere gratitude and appreciation to my supervisor, Dr. Yang Jinglei, for his guidance, patience and encouragement during my studies at NTU. The knowledge he gave and shared granted me great help not only for the past and current research work, but also for the future work. At the same time, I would also like to appreciate Dr. Jiang Zhenyu from South China University of Technology for providing me with valuable advice and supporting me to complete my work. I want to acknowledge Nanyang Technological University for the financial support and the research scholarship of this project.
