Influence of fibre on mechanical behavior of Ramie fibre /polystyrene hybrid composite

Abstract

Natural fibre composites are now commonly regarded as a reinforcing component in polymer matrix composites. For their biodegradability, less density, and higher specific characteristics, polymer matrix-reinforced natural fibre composite materials are commonly employed in industry. The tensile characteristics of Ramie fibre woven fabrics and Polystyrene (PS) composite laminates were investigated and impact tests, to examine how the volume percentage of the fibre influenced them. In the beginning, the thermal-compression method was used to create composite laminates with varying fibre volume fractions by layering different fabrics. The mechanical characteristics of material are determined by conducting tensile, shear and biaxial tensile testing. Additionally, an effect hammer testing was done to determine the frequencies as well as restraining properties of stratified composite structures. The viscoelastic behavior of Ramie fabrics/PS composite laminates changes to elastic as the volume percentage of the fibres increases. Tensile strength is enhanced by increasing fibre content. On the other hand, the increased fibre volume has an effect on the natural frequency and damping ratio.
