EFFECT OF TITANIUM DIOXIDE AND TALC ON THE TENSILE STRENGTH OF COMPOSITE MATERIAL

Abstract

Epoxy was incorporated with titanium dioxide and talc at different concentrations (0, 0.5, 1, 2, and 4 wt%), and then that mixture was combined with carbon fiber via a hand lay-up process. The mechanical properties of the composites were determined using universal tensile testing. The tensile test results revealed that the mechanical properties of the polymer matrix composites were increased as a function of talc and titanium dioxide concentrations. The best tensile strength of the composite was obtained from the 0.5% talc and 1% titanium dioxide sides. Increasing the weight ratio of talc 1%, 2%, and 4% and 0.5%, 2%, and 4% of titanium dioxide in composite production doesn’t exhibit a significant difference. Tensile testing behavior of talc and titanium dioxide reinforced composite specimens shows better results compared to unreinforced carbon fiber composites. As a result, this study provides a detailed explanation of how to improve the strength of carbon fiber composites.
