MECHANICAL PROPERTIES OF GREEN COCONUT FIBER REINFORCED HDPE POLYMER COMPOSITE

ABSTRACT: During the last few years, natural fibers have received much more attention than ever before from the research community all over the world. These natural fibers offer a number of advantages over traditional synthetic fibers. The present study aims to determine the mechanical properties namely, Tensile strength (TS), Flexural strength (FS), and Impact strength (IS) of green coconut fiber reinforced HDPE polymer composite material. Experiments are planned to produce the test specimens according Taguchi's L 9 orthogonal arry concept. The control parameters considered were fiber volume fraction (V f ) and fiber length (f l ). An attempt has been made to model the mechanical properties through response surface methodology (RSM). Analysis of variance (ANOVA) is used to check the validity of the model. The results indicated that the developed models are suitable for prediction of mechanical properties of green coconut fiber reinforced HDPE composite
