Natural fiber-reinforced polymeric composites are gaining a lot of attention in engineering applications because of growing environmental concerns. This study explores the diversity in properties due to the effect of fiber loading (10 wt%, 15 wt%, and 20 wt%) of reinforced hybrid epoxy composites using a novel combination of natural fibers: rattan mat and wastage short hair fibers. Experiments are conducted according to the ASTM standards for evaluating mechanical (tensile, flexural, impact, and hardness) and physical properties (water absorption and biodegradability). Tensile, flexural, and hardness properties, as well as weight loss percentage and water absorption percentage, indicated incremental behavior with increasing fiber loading, whereas for the impact test, it is the opposite. The Fourier transform infrared spectroscopy of composites was carried out to examine the details of chemical composition. Surface morphological analysis of the tensile fracture surfaces reveals the interfacial bonding characteristics between fiber and matrix. Thermo-gravimetric analysis was also used to evaluate the composite’s thermal stability.
