Effects of nanoparticles and fiber type on Hybrid blend Composite materials Behavior of epoxy and phenol formaldehyde.

Abstract

Composite materials are quite common today and are used in nearly every segment of civilian and military industry. The idea of reinforcement is not new. Over the centuries natural fibers, have been used to improve the strength and to lessen shrinking of pottery prior to firing and increase the strength in mud houses. This idea in the present form has been exploited with the development of glass, carbon and later of aramid .fibers Phenol formaldehyde resins were mixed with epoxy resins in different proportions to form a hybrid mixture of composite materials. It was reinforced with carbon fiber, glass fiber and Kevlar fibers, as well as reinforced with magnesium oxide (MgO) and zirconia (ZrO₂) nanoparticle particles, to study the effect of fibers and nanoparticles on the behavior of hybrid composites, namely, tensile, bending, hardness, Toughness. The results showed an improvement in the properties of the hybrid mixture after the use of fibers and nanoparticle enhancement.
