Recently, the use of composite materials in different applications like aircrafts, wind turbines and towers has developed rapidly. This rapid development of large size composite structures is, though, not without its problems, particularly in case of difference in lamination when using various materials. Health monitoring and delaminating preventive maintenance are important issues when using composite materials. The use of smart structures enables real-time monitoring of the composite materials and permits applications using sensors to appropriately arrive to a desired state. This paper presents an optimal, inexpensive and continuous laminated sensor based monitoring in composites using Fiber Bragg Grating (FBG). This paper investigates layered composites and FEM based on the static and dynamic equations and the mechanical behavior with respect to stress and strain. Delaminating criteria of a composite cantilever beam can be analyzed based on wavelength shifting relations of FBG and in the resulting reflected spectrum caused by applied forces or displacements.
