Investigation of the Effect of Nano Particles on Visco-elastic Behaviour of CFRP Hybrid Nanocomposites

Abstract

The aim of the study is to do an experimental analysis and investigation of visco-elastic behaviour of CFRP hybrid nanocomposites, which contains the small percentage of nanoclay and nanoZnO particles mixed for the improvement in the various properties of the CFRP composites. Also there is try to focus on the combined effect of another variable, i.e., fiber angle of orientation along with changing the percentage of nano particles.A hand layup method followed by process of vacuum bagging was used to make the samples of composite. Dynamic mechanical analyzer (DMA) was used to inspect the dynamic mechanical properties of CFRP hybrid nanocomposite specimens with changing temperature. The OVAT analysis is carried out for three mentioned variables and studied effect of variables on the various visco elastic properties like flexural storage modulus, loss modulus, Glass transition temperature and tan etc. It is found that due to the presence of nano particles there is tremendous change in the value of storage modulus ,it gets almost doubled, i.e., 200%because of the presence of nano particles. The experimental result also shows the positive effect on the loss modulus because of the nano particle contribution .Similarly there is considerable change in GTT(Glass transmission temperature) and change in length in DMA (Dynamic mechanical analysis ).
