Toughening effect
WebSep 1, 2015 · The actual effect of nanoscale CNTs on the toughening mechanism is still unclear. To the best of our knowledge, there are not many studies reported on the predominant toughening mechanism in CNT-filled epoxy polymer. Therefore, it is highly imperative to clarify the role of CNTs on the toughening mechanism of polymer … Rubber toughening is a process in which rubber nanoparticles are interspersed within a polymer matrix to increase the mechanical robustness, or toughness, of the material. By "toughening" a polymer it is meant that the ability of the polymeric substance to absorb energy and plastically deform without fracture is increased. Considering the significant advantages in mechanical properties that rubber toughening offers, most major thermoplastics are available in rubber-tough…
