Investigation of Mechanical Properties of Unidirectional Fibrous Composite by Micro-Mechanics Model

The use of advanced composite materials reinforced with fibers is expanded in these years. The main reason for the increased use of these materials is their high strength and hardness coefficient, their density and low prices. So, the fiber-reinforced composite materials can be used in the design of structures that require high strength to weight ratio and hardness coefficient. In order to replace these materials and new applications, many research programs to study the mechanical behavior of these materials has shifted.
