This paper investigates the effect of blending epoxy and reactive polyester on the mechanical properties on the ensuing laminate in different percent by weight. The laminate with hybrid polymer were tested using ASTM standards for tension, compression, interlaminar shear strength, impact, hardness, fracture toughness and rheological properties which are evaluated as a function of the blending. From the results it was observed that there was an improvement in the strength and fracture toughness. The blended polymer composites containing three different ratios of epoxy: polyester at 50: 50, 60: 40 and 40: 60 by weight. The blend containing 40 wt.% of polyester and 60 wt.% of epoxy showed enhanced tensile adhesive strength, impact strength, hardness and enhanced fracture toughness in comparison to the unmodified samples exhibiting a synergic effect.
