Abstract

It is well-known that woven fabric composite materials have high performance. It is, however, very difficult to access their mechanical behaviours due to their complexity of microstructual morphological geometry. Authors proposed Optical Coherence Straingraphy (OCS), which could visualize micro mechanical information tomographically and nondestructively from speckle deformation between synthetic images obtained by Optical Coherence Tomography. This is basically constructed by recursive cross-correlation technique and weighted moving least square method, which can offer cross-sectional strain distribution at the resolution of micrometer scale. In this study, applying OCS to plain-woven fiber-reinforced rubbers, the micro mechanical behaviour under uniaxial tensile load was visualized as an experimental strain distribution, which was verified by the numerical results based on image-based simulation. Consequently, tomographic strain distributions calculated by OCS agreed qualitatively with the simulated ones at the resolution of micro scale. It was, therefore, concluded that OCS could provide an experimentally powerful concept for the microstructual design of composite materials, as a nondestructive visualizing tool.
