Mechanical properties of hybrid composite glass fiber and kevlar fiber reinforcement with nano alumina

Composite materials are one type of materials, which reinforced by particles, fabrics or plates of another type. They consist of fibers and materials that keep these fibers known as a matrix that improves the stiffness of the composites, these fibers are widely used to strengthen polymeric. In this paper, the mechanical properties of Kevlar/glass fiber hybrid composite laminate with nanoparticles will be studied. Composite laminates with an epoxy matrix reinforced with twill Kevlar weaved fiber and plain glass was woven fiber. Three different types of composite laminates were manufactured, polymer composite with nanoparticles (AL₂O₃), polymer composite with glass fiber, and polymer composite with glass fiber and Kevlar. The effect of Kevlar/glass fiber content on the mechanical properties are studied such as hardness, tensile, and impact. The results indicated that hybridization of Kevlar fiber to glass fiber with nanoparticles improved the hardness values, impact energy absorbed, and tensile strength of fibers that were spun with Kevlar fibers and of composite laminates with nanoparticles.
