Phenolic resin is an artificial resin that is often synthesized from phenol and formaldehyde Synthesis of phenolic resin from cashew shell waste material, phenol and sulfuric acid catalyst with different ingredients at 1500C temperature for 90 minutes The resulting resin has low residue of unreacted cashew shell residue, the functional group composition is similar to that of commercial phenolic resin sample Research on fabrication of wooden ceramic samples using phenolic resin as binder from cashew shell waste material with different rates The mixtures were formed by hot pressing at 1800C for 3 hours and then sintered at 9000C in an oxygen-deficient medium After heating samples, the properties of flexural strength, porosity, FT-IR, XRD, SEM will be determined compared with ceramic samples using turpentine as binder The results obtained will contribute to waste disposal for the cashew industry and further research on woodceramic materials

Keywords: Liquefied wood, Phenolic resin, Cashew nut shell waste, Woodceramics
