摘要：
Three types of carboxyl-functionalized multi-walled carbon nanotubes (MWCNTs) were used to manufacture MWCNT-modified laminates. The effects of the MWCNTs on the mode I interlaminar fracture toughness and the fracture propagation were investigated experimentally. Fractured surfaces were inspected with SEM micrographs to justify the effects of MWCNTs on the mode I fracture of the laminate. The short-thin MWCNTs in a weight ratio of 0.3% increases mode I interlaminar fracture resistance of the laminate by about 2 times. The effects of long-thin and long-thick MWCNTs are quite low. Polymer crazing is the most important mechanism to improve interlaminar fracture properties.
