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

TGA, DSC, DTG Properties of Epoxy Composites Reinforced with Feather Fibers of 'Emu' Bird

Abstract: The use of composite material in engineering application is increasing. Now a day's researchers are focusing on natural fiber composites. In the present work composites were prepared with epoxy resin and emu bird feathers as fiber. The composites were prepared by varying percentage weight (P) of emu fiber ranging from 1 to 5 and length (L) of feather fibers from 1 to 5 cm. The thermal properties like Thermo Gravimetric Analysis (TGA), Differential Scanning Calorimetry (DSC) and Degradation Temperatures for the emu feather fiber epoxy composites were analyzed
