Dynamic Behavior of Hybrid Unidirectional Without Cracked Composite Plate

Luay Sadiq Al-Ansari, Haneen Hasan

Abstract


The composite material is one of the most common materials used in engineering applications due to the wide range of properties, high strength, cheap, easy to manufacture and lightweight. Therefore, many studies and researches have been conducted and are currently being conducted to obtain the appropriate mathematical models that describe the behavior of these materials when exposed to different types of mechanical loads. A mathematical model was built by using ANSYS (2D, 3D) models to represent composite materials. The composite plate was taken as a sheet made of longitudinal fiber and resin.  There are many types of fibers such as (carbon, glass, and Kevlar) and resin such as (polyester and epoxy). The volume ratio of the fibers in composite plate are (10%, 15%, 20%, 25%, 30%, 35% and 40%) in each types of resin. The effect of fiber volume fraction, types of fiber and types of resin on the equivalent longitudinal and transverse modulus of elasticity and equivalent Poisson's ratio were studied. The natural frequencies were calculated for all types of composite plates with simply support from each edge (SSSS).
