In this present study for light weight and low-cost engineering applications, high toughness epoxy biocomposites were made using Caryota urens woven (CUW) fibre and coconut husk biochar (CHB) particle. The major goal of this study was to see how adding CHB particles to an epoxy resin composite containing CUW fibre affected the characteristics of the composite. Biochar was made from coconut husk utilizing a low-temperature pyrolysis technique in this study. The composites made with 5% CHB have the maximum tensile strength of 188 MPa. Similarly, a CHB concentration of 7% in epoxy resin reduced wear volume to a higher extent. Furthermore, the composite produced with 7vol. percent CHB had the highest dielectric constant and loss factor of 5.6 and 0.78, and a thermal conductivity of 0.34 W/mK with a larger contact angle of 72 degrees. SEM scans revealed a heavily adherent phase of CHB in the epoxy resin matrix. Electrically stable composites with increased mechanical qualities could be employed in engineering applications such as insulation covers, higher current transmission tunnels, and the automotive industry.
