This study investigates the tensile and flexural behavior of hybrid polymer composites reinforced with hemp fiber, S-glass fiber, and carbon nanotube (CNT) nano-fillers using an epoxy resin matrix. The composites were fabricated through the hand lay-up process, incorporating varying fiber weight ratios and CNT contents (1–2 wt.%). Tensile and flexural tests were conducted following ASTM standards to evaluate the mechanical performance. Results revealed a consistent increase in both tensile and flexural strengths with increasing CNT content and S-glass fiber proportion. The highest tensile strength of 66 MPa and flexural strength of 73 MPa were observed for the composite containing 20% hemp, 20% S-glass, and 2 wt.% CNT. The improvement is attributed to enhanced interfacial bonding and load transfer due to the synergistic effect of micro (S-glass) and nano (CNT) reinforcements. The study demonstrates that hybridization of natural and synthetic fibers, combined with nano-fillers, can significantly enhance stiffness, strength, and overall structural performance. These hybrid composites offer a sustainable, lightweight, and high-performance alternative for automotive, aerospace, and structural applications. Future work may focus on optimizing CNT dispersion, analyzing dynamic and thermal behavior, and exploring bio-based resins to improve environmental sustainability
