EVALUATION OF MECHANICAL PROPERTIES OF NATURAL KERATIN FIBRE WASTE REINFORCED POLYPROPYLENE COMPOSITESGOVINDARAJU RAJKUMAR AND JAGANNATHAN SRINIVASAN
Natural keratin fibre waste (wool) reinforced polypropylene (pp) composites were fabricated by compression moulding technique by varying the fibre weight fractions (20%, 30%, 40%, 50% and 60%). The influence of fibre weight fraction on mechanical properties of the composites was investigated. It was observed that the composites containing 40% fibre weight fraction has given better mechanical properties of 14.62 MPa, 196.64 MPa, 12.84 MPa, 274.14 MPa and 12.82 Kj/m2 respectively for tensile strength, tensile modulus, flexural strength, flexural modulus and impact strength. It was also observed that the incorporation of waste wool fibres in polypropylene resin has improved the mechanical properties when compared to polypropylene composite.
