In this current research, the hybrid composites are made up of quick-set ARALDITE epoxy resin LY556 with a density of 1.18 g/cm3 and molecular weight of 190 g/mol. The cardanol oil used in this study was having a density of 0.930 g/cm3 and was prepared by self. Similarly, the cassava peel (CP) biochar was prepared in a programmable muffle furnace (Matrix Scientific, India) with an N2 inlet. The preparation of cardanol oil and cassava peel biochar is explained further in a detailed manner.
