The demand and applications of bolstered plastics such as natural, attainable, biodegradable, and fibres were developing worldwide in industries beginning from home utilities to aerospace applications. The high cost and weight of synthetic fibres were bolstered by a multitude of concerns. Subsequently, it is far vital to create a natural fibre combination with a matrix to accumulate the most efficient common presentation. In this present study, a composite is made of a natural fibre (jute) reinforced with vinyl ester resin with and without a filler (SiO2). Untreated jute fibres are utilised as reinforcement, while filler materials were used to increase the characteristics of jute fibre and analyse the impact of filler material in the composite. The produced composite was tested for tensile strength, compressive strength, flexural strength, and hardness. The SEM study of the fracture surface was also evaluated in the present study. Filler-mixed composites have a 50 percent higher tensile strength than those without fillers, and the remaining attributes have enhanced by at least 5 to 10%. From analysis, filler-mixed composites hold a good mechanical property due to fibre-filler bonding with the help of vinyl ester resin.
