Investigations of the influence of hexagonal boron nitride particulates on mechanical & tribological properties of PA66

Abstract

The present research investigates the influence of hexagonal boron nitride (h-BN) particulates on PA66 composite's mechanical and tribological properties. The compounding of 5wt% h-BN and PA66 matrix was done with the help of twin-screw extruder. Specimens of pure PA66 and PA66/h-BN composites were prepared by the injection moulding process. Mechanical and tribological properties i.e. tensile strength, modulus of elasticity, Rockwell hardness, friction coefficient and wear rates were measured in this research to quantify the different properties of materials. Results shows that the modulus of elasticity and Rockwell hardness of composites were improved while the tensile strength was found decreased in negligible amount compare to pure PA66. The h-BN fillers were found to be effective in reducing wear and friction of PA66/h-BN composite in tribological testing.
