Description Hessian cloth (jute fabrics) samples were soaked in the alcoholic shellac solution and dried at 333 K for 4 hours. Six layers of shellac treated hessian cloth were heat pressed (373 K for 10 min at 5 MT pressure) to fabricate biocomposite and then its mechanical properties were
evaluated. To improve the mechanical properties of the
biocomposite, a series of formulations was prepared using
varying percentages of urea (0.25 to 30 %) with shellac in
methanol; then the composite was fabricated using same
parameters. Mechanical properties such as tensile strength (TS), bending strength (BS), tensile modulus (TM), bending modulus (BM), elongation at break (Eb), impact strength (IS) of the biocomposite were determined. Percentage of
urea and soaking time of hessian cloth for the composites
were optimized over mechanical properties. The biocomposite prepared with 0.5 % urea at 2 min soaking time showed the highest mechanical properties (TS – 79 MPa, BS – 74 MPa, BM – 7 GPa, IS – 13 kJ/m2 and Eb – 11.3 %). Scanning electron microscopic images of the fracture surface of the composites were suggested.
