EFFECT OF ANGLE PLY ORIENTATION ON WEAR PROPERTIES OF RAMIE FIBRE REINFORCED POLYMER COMPOSITE

Abstract

The influence of angle orientation on the wear factors of materials reinforced with ramie fibers is studied in the present work. In this study, ramie fiber-reinforced composites were fabricated by a hand-layup process using a thermoset matrix. The composite specimens were produced by developing a variety of fiber orientations, including [0°/0°/0^o/0^o], [0°/90°/0^o/90^o], [45°/-45°/45^o/-45^o], and [0°/45°/-45°/90°] in four layers. Using a pin-on-disc tribometer, the wear characteristics of the composites were evaluated during dry sliding conditions. Different weight types were used in the trials, as were sliding speeds and sliding distances, to completely capture the wear behavior. Additionally, wear increased as sliding speed and weight increased, regardless of fiber orientation.
