Influence of CNT Particle on Mechanical Properties Of Epoxy Composites

Abstract

In the recent years very much rapid development in the field of nanotechnology in many applications like structural, medical, biotechnology, agriculture etc. Polymers and polymer based composites attain a vital role in structural applications due to its light weight, easy of handling etc. However, during processing of polymer few problems associated with crosslinking of polymer bonds. These problems are overtaking by reinforcing Nano particles to the polymers. This research work focusses on studying the mechanical properties of epoxy polymer composites by reinforcing various weight percentage of Carbon Nanotube (CNT). The epoxy composite is prepared by magnetic stirring, mechanical stirring using hand layup method followed by post curing. The one-way ANOVA used to study the descriptive statistics influence of CNT reinforcement from 0.2 to 0.8 weight percentage in a 0.2 intervals. Further, Scheffe multiple comparison, Turkey HSD and Holm and Bonferroni multiple comparison tests are used to study the significant effect between the reinforcing percentage. It was observed that adding CNT to the composites improves the tensile strength and it is also observed from F and P values that reinforcement statically significant.
