Abstract
This study explored the effectiveness of hardened epoxy containing pear cactus fiber and onion sheath biocarbon nanosheet. Mechanical, dielectric, and thermal properties of pear cactus epoxy composites containing varying volumes of biocarbon nanosheet are the focus of this investigation. For this study, biocarbon was extracted by pyrolysis from red onion peel. For 3 vol.% of biocarbon, tensile strength was up to 63%, and flexural strength was up to 44% higher than pure epoxy. The addition of reinforcements boosted the Izod impact toughness and hardness values by around 5 volume percent to roughly 94% and 92%, respectively. When biocarbon made up 5% of a material’s volume, improvements in dielectric constant and loss were around 5.8 and 0.23, respectively. The inclusion of biocarbon increased the thermal conductivity to a high of 0.44 W/mK. These composites might be used as a shielding material because to their improved dielectric, mechanical, and thermal activities.
