Mechanical properties of carbon nanotube–polymer composites

Carbon nanotubes (CNTs) are the most promising and extensively used filler material for composite reinforcement due to their exceptional mechanical properties. In this chapter, we discuss the advancement so far in the area of mechanical reinforcement of polymer matrix systems using CNTs. Firstly, the fundamental of CNT structure and the polymer matrices used in CNTs are introduced and the basics for effective reinforcement are presented. The evolution and most recent stage in the development of various processing and manufacturing techniques for CNT-reinforced composites is discussed. Moreover, we discuss the system requirements and factors influencing the mechanical behavior of CNT-based nanocomposites. Also, the effect of CNT/polymer interfacial characteristics and filler dispersion state on the mechanical properties and damage profile of the nanocomposite materials are discussed. Finally, we conclude by emphasizing the feature perspective and challenges for the development of CNT-based nanocomposites that may find use in future high-performance material applications.
