Natural fibre reinforced polymer composites (N-FRP) have gained popularity in recent years as an alternative to regular polymer composites, owing to growing environmental concerns. Natural fibers are becoming increasingly popular due to their outstanding properties such as flexibility, strength, compatibility with living creatures, and impact resistance. A notable application of natural fibers is in the medical industry, with the goal of producing cost-effective, sustainable, and long-lasting products. Combining different fibers in the matrix can improve a material’s mechanical characteristics in a hybrid method where one type of fibre can compensate for the deficiencies of another. Since the volume of fibers greatly affect the mechanical characteristics of hybrid composite materials, our present study is to investigate the effect of volume fraction of jute and sisal fibers on tensile strength of hybrid composite followed by machining using rotary electrochemical discharge-based machining (R-ECDM) process. The holes are fabricated at different electrolyte concentration and rotation of the tool. The hole overcut (HOC), Circularity error (CE) and surface roughness (SR) of the machined hole is analyzed to study the impact of input process parameter. ECDM applies the principle of thermal heating and chemical etching to remove the material and effectively applied for non-conductive brittle materials. The article’s originality lies in the combined characterization study of hybridized N-FRP and its machining using R-ECDM. The tensile strength of composites improves as the volume of fibers increases due to the influence of individual fibre strengths. The proposed machining method is analyzed for machinability study of the N-FRP hybrid composites. The rotational effect improves the HOC, CE and surface roughness of the machined hole due to enhanced circulation of the electrolyte. The input parameters significantly affect the input parameters since all response parameters increases with the increase of electrolyte concentration and at higher level of tool rotation.

Keywords: Natural fibers, hybrid composite, volume fraction, ECDM, sparks, surface roughness.
