Numerical Modelling of Layered Composite Materials with Embedded Optical Fiber Sensors

Abstract:

One of the crucial points in making materials with embedded optical fiber sensors is obtaining information about stress-strain state which helps to asses the influence of embedded optical fibers on integral mechanical properties of the structure and redistribution of stresses and strains in the area around optical fibers. In this paper models of woven composite material with embedded optical fibers are studied with numerical results achieved with the help of finite element method in case of GFRP VPS-33 material with fabric filler T-10-14 and epoxy resin ENFB-2M. Numerical results about the change of stiffness parameters of plate specimens in cases of tension and bending are obtained. Evaluation of stress state change near embedded optical fiber in different cases of optical fiber orientation with respect to loading and in the presence and absence of resin pocket defect with polyamide optical fiber coating taken into account is given in this study.
