Effect of Chemical Treatment on The Some Electrical And Thermal Properties For Unsaturated Polyester Composites Using Banana Fibers

Abstract

This study was carried out to investigate the effect of the chemicaltreatment of banana fibers on the physical properties of composites. Banana fiberswere treated with 10% sodium hydroxide and some physical tests were carried outlike: dielectric strength, dielectric constant, and thermal conductivity. The resultswere compared with untreated fibers composites and virgin unsaturated polyester.The results showed that the chemical treatment improved the dielectric strengthand thermal conductivity by about 29.37% and 139% respectively compared withuntreated fiber composites. Finally, the dielectric constant value of the treatedfiber composite was found to be lower than the untreated fiber composite andvirgin unsaturated polyester.
