Effect of Nano Clay inclusions on Mechanical Properties of Thermoplastics

G. Surya Rao and Prof. H. Ravi Shankar

ABSTRACT: 

Polymer has been widely used now-a-days in many fields. Their properties make them useful in much engineering applications. Owing to their poor mechanical properties in engineering applications are seldom found. Hence, in the present study it is aimed to enhance the mechanical properties of thermoplastics to enable their usage in engineering applications such as automotive bumpers, gears etc. Recently many researchers tried to improve mechanical properties of polymers using Nano clay inclusions. In the present study polypropylene (PP), Acrylonitrile butadiene styrene (ABS) and high density polyethylene (HDPE) thermoplastics polymers are considered. Nano clay included polymer composites are fabricated with an intention to enhance their mechanical properties. Often these materials are subjected to various testing procedures and mechanical properties of these composites are to be studied. Hence, in the present work PP, ABS and HDPE Nano clay composites are fabricated using twin screw extruder for blending Nano clay in different percentage to study the effect of Nano clay weight fraction on these properties. Samples fabricated using injection molding process. The samples are fabricated at different weight percentages of nanoclay and Often these materials are exposed to certain testing like tensile and fatigue. More after the mechanical properties of PP, ABS and HDPE with Nanoclay polymer composites were observing and how much percentage of strength increasing when comparing with the pure samples. Among the selected thermoplastics ABS Nano composites exhibits higher mechanical properties and by increasing the nanoclay weight percentage in each and every component the mechanical properties also increasing gradually and all are exhibits their better results at 5% of nanoclay with PP, ABS and HDPE.
