Abstract: In the present work an attempt has been made to develop Bio-composite Material using raw dupion silk fiber reinforced vinylester matrix in addition with gelatin as filler material with varying percentage using hand lay-up method. The experiments namely tensile, flexural and hardness test were conducted on the standard samples prepared. An appreciable improvement was found in the mechanical properties of the Bio-composite, which can be used for variety of applications in the human bone replacement. The biocomposites were prepared in varying percentage of filler addition (0%, 10%, 20%, and 30%) and different mechanical tests (tensile, flexure and hardness) were conducted on the samples prepared as per ASTM standards. According to literature survey the human femur bone with tensile strength for female is 30.08±7.96MPa. In this work it was found that tensile strength of 30% gelatin filled with Dupion silk fiber reinforced vinylester bio-composite material is 26.86 MPa
