Development of HDPE composites with improved mechanical properties using calcium carbonate and NanoClay

Abstract High density polyethylene (HDPE) binary and ternary composites were developed reinforcing coated calcium carbonate (CaCO3) and NanoClay for various industrial applications. The fillers were melt blended with HDPE using Brabender mixer and sampled using compression molding. The effects of fillers on tensile strength, toughness, impact strength and hardness were analyzed and significant improvement was observed in both binary and ternary composites. The results showed that Young's modulus was increased up to 22.5% for the ternary Nanocomposite. The addition of CaCO3 showed more promising data as compared to ternary composite i.e. 27.7% increase in tensile strength, significant increase of up to 118% in toughness, 55.4% and 15% increase in impact strength and hardness respectively.
