Toughening mechanisms summary

Summary of Different Toughening Mechanisms. In toughened polymers with a dispersed modifier phase (i.e., in the dispersed systems), the three mechanisms sketched in Figure 19 may, in general, be distinguished. The characteristics of these different mechanisms are as follows. 

The properties of the various composite systems are discussed, with an emphasis on toughness a comprehensive comparative summary is provided, together with a discussion of the possible toughening mechanism that may operate. The extraordinary stififiiess and specific tensile strength of CNTs makes them well-suited for use as reinforcing elements in polymer composites. The incorporation of carbon nanotubes can greatly increase...
