Abstract

Following a number of essential considerations concerning smart materials and structures as well as the structural diagnostics issues involved with the use of optical fibers in composite materials, the paper builds on earlier theoretical study of the micromechanics of laminae reinforced with multidirectional fibers, proposing that optical fiber grids embedded in matrix material be used to improve strength and monitoring performance. The paper then addresses the static characterization of such laminae, detailing previously obtained results for multidirectional generic fiber grids. For any given percentage fiber content, a numerical application demonstrates that laminae reinforced with a right triangular grid of optical fibers show consistent improvement in their extension and bending stiffness characteristics as compared with laminae reinforced with unidirectional fibers.
