Abstract

Composite materials are being used in more variety of products and applications, as more and more industries realize the benefit of these materials offers for light-weight composite structures for aerospace, transportation, marine and electronics system develop to need the mechanical testing requirements for composite materials, components and structures. The nanocomposites are materials that incorporate nano sized particles into a matrix material. The result of the addition of nanoparticles is a drastic improvement in properties that can include mechanical strength, toughness, hardness, stiffness and electrical or thermal conductivity.The high-density polyethylene (HDPE) is used as matrix material and filler material called reinforcement material as nanoclay cloisite 30B and rice husk ash. HDPE grafted with maleic anhydride (HDPE-g-MA) compatabilizer was used to get betterblending of polymers that will increase their stability and better interaction between the high density polyethylene and nanoclay with rice husk ash. These nanocomposite materials were prepared by meltblend compounding in a twin screw extruder machine with a spindle speed of 60rpm with variouszone temperatures.The equal addition of nano clay and rice husk ash in the range of (0-4wt %) with HDPE.The injection moulding machine was used to prepare specimens fordifferent mechanicaltestssuch as flexural, tensile, hardness and impact using corresponding dies as per ASTM standard. Morphological study and particle distributions were studied using the scanning electron microscope analysis.The mechanical properties of HDPE nanocomposites were examined with the effect of four different wt % of nanoclayto identify the most effective wt % of nanoclay toimprove the strength of nanocomposites. The experimental results on mechanical properties of HDPE/ cloisite 30B nanoclay and rice husk ashcould be analysed and improvement of strength of materials were studied with various wt% (0 to 4%) ofnanoclay and rice husk ash on HDPE nanocomposites.
