Abstract

Different approaches have been attempted to use biomass as natural biopolymer for production of biodegradable plastics. Use of this biomass can open a new avenue for the utilization of agricultural residues at the same time adds value to the construction of rural agricultural based economy. Also highly natural fiber filled composite materials lead to reduction in the use of petroleum based materials which eventually leads to a reduction in the green house gas emission. In this work the influence of empty fruit brunch fiber EFBF and cellulose derived from EFBF loading on the mechanical properties of polypropylene PP was comparatively studied. Two different sets of polypropylene biocomposites containing 10 0.2 0.3 40 and 50 cellulose and EFBF were prepared in a twin-screw Brabender compounder. The significant increase in the tensile strength and flexural strength of the PP-cellulose biocomposite implied the toughness and stiffness of the PP with increase in the cellulose content further supported the previous evidences. The enhancement of the mechanical properties of PP with cellulose is believed to be attributed to the better bonding capabilities of cellulose with the polymer matrix along with improved dispersion of cellulose fiber strengthening the PP biocomposite. Affirmation from the morphological analysis using scanning electron micrographs was also used to support this context. The decline in tensile strength and flexural modulus of PP-EFBF biocomposite with the increase of EFBF is associated with poor fiber dispersion and fiber matrix adhesion.
