Abstract
The strength of the unidirectional composites depends on factors like types of the fibers, types of the matrix, the volume fraction of fibers (Vf), volume fraction of matrix (Vm), angle of fibers to the horizontal axis, etc. If the direction of fiber and the applied force is the same then the angular orientation is 0° and the composite behaves like an isotropic material. In this condition, if extensional stress is applied to the composite then predominantly extensional strains are generated. In the same condition, if shear stress is applied to the composite then predominantly shear strains are generated. If the direction of fiber and applied stress is not the same then the composite behaves like an anisotropic material. In this condition, if extensional stress is applied to the composite then both extensional strains and shear strain are generated in the same component. In the same condition, if shear stress is applied to the composite then both shear strains and extensional strains are generated. So, as the angle of orientation increases, the behavior of composite moves from isotropic material to anisotropic material. The maximum value of the angle of orientation can be 90° when the fiber is oriented in the lateral direction. At such orientation, the tensile strength of the composite depends on matrix and the fibers act as stress concentration factor (SCF). Therefore, fibers have a negative influence on the tensile strength of the composite. The elastic behavior of Carbon Fiber Reinforced Composites (CFRC) was studied as a function of the angular orientation of the carbon fiber in the composite. The change in modulus of elasticity, as well as variation of stress and strain with an increase in the angle of orientation the carbon fiber, were calculated by theoretical approach. The results of the same are presented here.
