Abstract: Carbon fiber reinforced plastics (CFRP) are widely applied in high performance vehicles due to their excellent nature, namely, high specific strength and modulus, tailorable mechanical properties, fatigue and corrosion resistance, and dimensional stability. Among all the CFRP components, laminated structure are most widely applied. However, due to the lack of reinforcement fibers within the interlaminar zone, laminated CFRP are highly susceptive to delamination and low velocity impact damage. Based on this background , the research progress of laminated plate anti-delamination damage methods is reviewed in this paper, the applicability, advantages and disadvantages of these methods are compared and expounded, and the research progress of using carbon nanotubes (CNTs) to lift laminated plates against delamination damage is summarized. The properties and toughening mechanism of carbon nanotubes, the toughening methods and effects of carbon nanotubes are summarized, and the possibility of further improving interlaminar properties of carbon nanotubes is discussed.
