Protein fiber hybrid composites using silk and wool fibersin polypropylene matrix are fabricated by compression moulding machine. The compression moulding conditions such as time, temperature and pressure are optimised to get better mechanical properties in the resultant composites. Box Behnken experimental approach is used with response surface methodology for optimization process.Composite samples are developed as per Box Behnken design and its mechanical properties are evaluated as per standards. The optimized conditions were arrived at a moulding temperature of 175 °C, at the time of 7 min and at the pressure of 44 bar. At this optimized conditions tensile strength of 23.29 MPa, flexural strength of 12.96 MPa and impact strength of15.91 KJ/m2is obtained in the protein fiber hybrid composites.
