Candlenut is a native tree in the Philippines. It is planted for the use of its timber and seeds. The seeds are harvested for the extraction oil which can be used in soap and candle making, wood preserving, and wood varnishing. In addition, candlenut oil contains a high number of unsaturated fatty acids which can be used as a building block for polymerization. This study aims to partially replace petroleum-based epoxy resin with candlenut oil. The biocomposite produced was tested for its flexural strength and water absorption. The results were compared with that of neat epoxy resin. Oil was extracted with an average yield of 38.5264%. The biocomposite was subjected to various parameters which are curing time (60 and 120 minutes), oil loading (5% and 15% v/v), and oil type (non-epoxidized and epoxidized). It was found that the biocomposite which exhibited greatest strength of 71.0969 MPa was at 5% non-epoxidized oil loading at 120 minutes curing time. The composite with the lowest water absorption of 0.2671% was at 5% epoxidized oil loading at 120 minutes. Two-way ANOVA was used to determine the significant factors and interactions.
