Abstract: | Static and dynamic mechanical characterization of MWCNTs reinforced Polyurethane composites has been performed by using Nano-indentation techniques. A load of 500µN has been applied during static characterization and properties like elastic modulus, hardness and fracture resistance have been evaluated. A significant improvement has been observed in static mechanical properties under the influence of varying composition of MWCNTs. Dynamic mechanical analysis has been performed for evaluating visco-elastic properties of composite material by varying the frequency of load in the range of 15-250Hz. A significant improvement of 80% in the storage modulus of composite material has been observed with a minor composition of MWCNTs (3wt %). Finite Element Analysis studies reveal that von Mises stresses have been reduced with the reinforcement of MWCNTs into crit ically stressed area. newline |
