The primary goals of the current study are to create and assess epoxy composites reinforced with three different natural fibers. A compression molding approach was used to manufacture the composite, which consisted of 45 wt% natural fibers and 55 wt% epoxy resins with hardener. The mechanical and physical characteristics of the created composites were evaluated and compared. The findings revealed that density decreased and water absorption increased with an increase in the weight percentage (wt%) of jute fiber and a decrease in the weight percentage (wt%) of palm leaf sheath fiber. In contrast, the weight percentage of areca nut sheath fiber and epoxy resin remained constant. Mechanical tests revealed that the increase in jute fiber (15–25 wt%) and decrease in palm leaf sheath fiber (25–10 wt%) with constant areca nut sheath (10 wt%) fiber enhanced the stresses (tensile, compressive, and bending) and Janka hardness and decreased the impact strength. Tensile and bending fractures indicate that strong interfacial bonding is achieved, resulting in the majority of locations exhibiting clear fractures rather than debonding.
