Phenol-formaldehyde resin was mixed with epoxy resin in different proportions to form a hybrid mixture of composite materials. It was reinforced with carbon fibers, glass fibers, Kevlar fibers, magnesium oxide and zirconia nanoparticle particles. This research investigates the effect of fibers and nanoparticles on the behavior of hybrid composites, namely, tensile, bending, hardness and toughness. The results showed an improvement in the properties of the hybrid mixture after the use of fibers and nanoparticle enhancement.
