Abstract: In this study, the study of mechanical properties of Kevlar/glass fiber hybrid composite laminate with nanoparticles. Composite laminates were fabricated using vacuum bagging process with a phenol-formaldehyde, epoxy matrix reinforced with twill Kevlar weaved fiber and plain glass was woven fiber. Four different types of composite laminates different (polymer composite and nanoparticles (AL O )), polymer 2 3 composite and glass fiber, polymer composite and glass fiber and Kevlar ) were manufactured. The effect of Kevlar/glass fiber content on the mechanical properties (hardness, tensile and impact ). Results indicated that hybridization of Kevlar fiber to glass fiber improved the hardness values, impact energy absorbed with a slight reduction of tensile strength of fibers that were spun with Kevlar fibers and of composite laminates.
