Study of the electric properties of palm fiber-reinforced acrylonitrile butadiene styrene composites

Abstract

The electrical properties like AC conductivity, AC resistivity, and dielectric constant of the palm fiber-reinforced acrylonitrile butadiene styrene composites were investigated using impedance analyzer at room and variable temperatures. Palm fiber was collected from 10 trees of different age group from Comilla region in Bangladesh. Three sets of samples were prepared for three different wt (%) (5%, 10%, and 20%) of fiber contents using Injection Moulding Machine. Each set has 10 composite samples in which first five of them are made with 11 to 20 years-aged palm fiber and latter five of them are made with 5 to 10 years-aged palm fiber. The AC electric conductivity increases with the increase of frequency, wt (%) of palm fiber in the PF-ABS composites, and with the increase of temperature. The AC resistivity decreases with the increase of frequency, with the wt (%) of fiber content in the PF-ABS composites and with the increase of temperature. Moreover, the comparison between the PF-ABS composites with 11 to 20 years-aged palm tree shows better result than 5 to 10 years-aged palm tree. The dielectric constant of the composites decreases with the increase of frequency. With the addition of palm fiber content in composites, dielectric constant increases. The dielectric constant also increased with the increase of temperature.
