| Abstract: | Natural fibers are largely divided into two categories depending on their origin: plant based and animal based. Plant based
natural jute fiber reinforced polypropylene (PP) matrix composites (20 wt% fiber) were fabricated by compression molding.
Bending strength (BS), bending modulus (BM), tensile strength (TS), Young’s modulus (YM), and impact strength (IS) of the
composites were found 44.2 MPa, 2200 MPa, 41.3 MPa, 750 MPa and 12 kJ/m2, respectively. Animal based natural B. mori silk fiber reinforced polypropylene (PP) matrix composites (20 wt% fiber) were fabricated in the same way and the mechanical
properties were compared over the silk based composites. TS, YM, BS, BM, IS of silk fiber reinforced polypropylene composites
were found 55.6 MPa, 760 MPa, 57.1 MPa, 3320 MPa and 17 kJ/m2 respectively. Degradation of composites in soil was measured upto twelve weeks. It was found that plant based jute fiber/PP
composite losses its strength more than animal based silk fiber/PP composite for the same period of time. The comparative
study makes it clear that mechanical properties of silk/PP composites are greater than those values of jute/PP composites.
But jute/PP composites are more degradable than silk/PP composites i.e., silk/PP composites retain their strength for a longer
period than jute/PP composites. |
