Experimental Analysis of Mechanical Properties of Nanocomposites Based on Poly amide 6/ EPDM /Carbon Nanotubes

In this paper, the mechanical properties of nanocomposites based on a matrix of two phases of polyamide 6 polymer and ethylene propylene diene monomer (EPDM) reinforced with carbon nanotubes are investigated. The compounds include 0%, 1%, 2% and 3% by weight of carbon nanotubes as well as 5 and 10% by weight of EPDM-G-MA as compatible and 10 and 20% by weight of EPDM prepared by an internal mixer. Samples were prepared for mechanical tests by a hot press machine. Mechanical tests were performed to determine the impact and tensile strengths, modulus of elasticity and elongation at failure. It was observed that adding 1% by weight of carbon nanotubes increases the impact strength by 12%, tensile strength by 25% and elastic modulus by 43%, but decreases the failure length by 13%. Also, with the presence of 10% EPDM, impact strength increased by 27% and elongation at fracture by 34%, but the tensile strength of polyamide decreased by 5% and its elastic modulus by 19%. To improve the mentioned cases, by adding 5% EPDM-G-MA, the impact strength increased by 14%, the tensile strength by 5%, the elastic modulus by 20% and the elongation at break by 13%. Finally, by adding carbon nanotubes and combining EPDM and EPDM-G-MA, all the mechanical properties mentioned in polyamide 6 were improved
