Abstract


Objectives: In this study stir processing method is used to increase the strength of polymer with the addition of reinforcements such as micro and nano silica, ZnO and chitin powder. Methods/Statistical Analysis: produced with this process are the production of parts having good resistance to solvents like HCl and H2SO4 being environmental friendly. Silica (micro and nano), chitin and ZnO were added into polyester resin in different fractions as 2%,4%,6% and 10% through mechanical stirrer at 1000 rpm for 1 h. Accelerator and catalyst were added and stirred using a glass rod. The influence of ZnO nano particles with the addition of silica and chitin powder on the mechanical properties like tensile strength and hardness were investigated. The comparison of different weight fractions is also studied. Findings: By adding ZnO nano particles with micro silica and chitin the tensile property of polyester composite was increased. The hardness increased with the addition of Silica (micro and nano) and ZnO whereas, it decreased with the addition of chitin powder. Application/Improvements: Investigating the effect of Silica (micro and nano) and chitin in addition to the ZnO nano particles on the mechanical and micro structure of polyester composites.
