摘要

Bio polymer derived from the biodegradable natural plant resources are getting wide attention in production of light weight high performance composite materials offsetting the utilization of fossil fuel based synthetic man-made polymers, due to their eco friendliness, lower environmental impact, and higher thermal stability. Even though, the challenges in achieving higher mechanical properties of biopolymers composites need to be addressed through adding the natural fillers and bio fibers in various proportions. This present work employs the Moringa Oleifera (MO) fibers, Polysaccharide (PS) fillers to reinforce with the polylactic acid (PLA) bio resin to fabricate the series of six different bio composites through compression molding method by changing the volume fractions of raw materials as 10:5:85, 15:5:80, 20:5:75, 10:10:80, 15:10:75 and 20:10:70% of MO short fiber, polysaccharides nano fillers and Polylactic acid respectively. The prepared bio composites were tested according to the ASTM standards for determining properties via tensile and impact test, thermal behavior by conducting viscoelastic properties, differential scanning calorimetry, and flammability analysis. Finally, the internal evaluation of the tensile tested samples was analyzed through scanning electron microscope (SEM). The addition of nano polysaccharides filler reduced the void content and increased the cohesion characteristics between the MO fibers and PLA bio polymers. Further, it causes to the higher tensile and impact strength than the pure polylactic acid material. Higher fiber volume and filler percentage influenced to attain better thermal stability than the lower volume considered in the present work. The fabricated ecofriendly biodegradable bio composites were attributed to the competent material properties and can be used in furniture, automotive, aerospace and packaging industries.
