Study on Effect of Nanosilica Sand Addition on Physicaland Mechanical Properties of Thermoplastic

Nanoparticles reinforced composite can be considered as a new technology and a good
candidate material for research. Since this advanced composite are relatively new,
studies need to be done to discover the properties changing in the composite. The aim of
this project is to investigate the effect of nanosilica sand addition on physical and
mechanical properties of thermoplastic. The thermoplastic that will be used in this
research is TITANZEX HI 1100 high density polyethylene while the nanosilica is in the
range of 0-100nm in size. The composite materials were manufactured using the
compression molding process. Testing shows that addition of nanosilica provides
improvement in mechanical properties of HOPE at low nanosilica percentage. The
optimumvalue of tensile strength, Young's Modulus and flexural strength is 11.23Mpa,
24.83MPaand 13.88MParespectively when the content of Si02 is 15 wt%. Testing also
shows that the density of the composite improves up to 1.35 g/cm3 at 20 wt% silica
content. This researchhas opened a new horizon for thermoplastic polymercompositeto
be use as construction material.
