Experimental Investigation to Evaluate Mechanical Properties on Nano Graphene Added CFRP Laminates

Abstract

Polymers are regularly supported by different estimated fillers to lighten a portion of the constraints of the polymers. The use of nanoscale fillers to work on mechanical and thermal properties of polymers have prompted to an extreme option for the conventional polymer composites. Their high strength-to-weight ratio, excellent mechanical properties, and resistance to corrosion make them ideal for use in creating lightweight and durable structures. The present work mainly focused on the carbon fibre(CFRP) added with Graphene filler with 3mm thickness and a layer thickness of 0.5mm in vacuum impingement moulding process with vacuum bagging at different pressures directions , number of layers and curing temperatures. Graphene Nano particles taken as filler content of 2% which has been done previously as pilot experiments and form literature. The design of experiments selected from Taguchi L9 orthogonal array to prepare samples. A three factorial study from Taguchi has been optimized to check the best parameters for improved mechanical properties in the composite. The direction of injection is taken as top, and diagonal as well as pressure 20 bar, 25 bar and 30 bar with curing temperatures after lamination is 60, 80 and 100℃.
