Studies from North Dakota State University in the Area of Composite Materials Described (Effects of MWCNT reinforcement on quasi-static and dynamic tensile properties of epoxy)

By a News Reporter-Staff News Editor at Journal of Technology -- Current study results on Composite Materials have been published. According to news reporting originating from Fargo, North Dakota, by VerticalNews correspondents, research stated, "The addition of damping to structural components holds potential benefits across many applications. However, the dynamic properties, including damping, are often considered independently of the quasi-static mechanical properties."

Our news editors obtained a quote from the research from North Dakota State University, "In this study, the effect of multi-walled carbon nanotube (MWCNT) content level was investigated for structural damping properties, including elastic modulus, toughness, loss modulus and glass transition temperature. The MWCNT reinforcement levels of 0.2, 0.6 and 1 wt% are compared with that of the neat epoxy. The largest property improvement found was an increase of 81% in the toughness of the 0.2 wt% composite over the neat epoxy. The dynamic mechanical analysis showed improvements in the loss modulus as the MWCNT content increased. The highest loss modulus, with a 15-20% improvement over the neat epoxy, was in for the 1 wt% composite."

According to the news editors, the research concluded: "Overall, the mechanical properties were improved by the addition of MWCNTs, though damping is limited at low material strain."
