|Abstrakt :||This work focuses on assessment of the real fiber and matrix volume ratios of unidirectional fiber composites which will be used in future micromodels. Scanning electron microscopy (SEM) was employed on samples with polished cross-sections.|
Obtained images of various parts of the composite cross-sections are processed using Matlab and its Image processing toolbox. The areas of the image corresponding to fibers are detected by correlation and fast Fourier transform.
The output of this analysis is a vector of centers and radii of all fibers and subsequently the fiber and matrix volume ratios are easily determined.
