Experimental Study on Mechanical Properties of PA66 Blended with MWNTs

Abstract:

A composite material is a macroscopic consolidation of two or more materials, having a detectable interface between them. A nanocomposite is the one which consists of two or more nanosized materials which are dispersed in a matrix in order to perk up the properties of the primary material. Polymer composites are prepared by dispersing strengthening fibres in the polymer matrix. A polymer nanocomposite consists of a polymer matrix with nanosized filler. CNTs are one of the most encouraging fillers because of their extraordinary properties and large aspect ratio. A microscopic amount of CNT can have an inquisitively large impact on the properties of a composite. CNTs have been well documented as nanostructural materials that can be used to alter mechanical properties of polymer-based composite materials because of their superior properties. In this research the properties, both elastic modulus and strength of Nylon-66 is improved by the selective addition of CNT. The main objectives include the study of the effect of CNTs content on the mechanical properties of Nylon 66. The composite is to be prepared at various compositions of CNT and material will be analysed by testing the mechanical properties using various test facilities. The finite element modelling of the test specimens were made and a Representative Volume Element (RVE) approach of finite element modelling is used to model the specimen. Mathematical calculations were performed to find out the modelling and RVE. The results are then compared and concluded.
