Influence of the addition of nano-Silica particles as reinforcement on the tensile yield properties of Polyamide 6 polymeric matrix used in medical applications

摘要

It is well known that the polymer matrix nanocomposites are one of the most important polymeric materials that are used in medical applications due to the exhibition of very good mechanical and thermal properties. In this study the authors have used Polyamide 6 (Nylon) polymer for preparing polymeric nanocomposite samples. Silica nano-particles have been used as reinforcement for reinforcing the polyamide 6 polymer matrix. After the sample preparation, influence of nano-particles on the tensile ultimate strength and tensile Young modulus of the Polyamide 6 has been investigated experimentally. It is found that using nano-silica can significantly improve the tensile properties of Polyamide 6 polymer. Test results shows that addition of nano-scale silica particles can modify the tensile characterstics of the polymer i.e. improve the tensile elastic Young's modulus of the polymer. Similar trend is observed for the tensile ultimate strength of polyamide 6 nanocomposites, where the presence of nano-silica modify the ultimate strength of the material.
