Analysis of fiber distribution, size, and volume ratio of unidirectional composite plates with different thicknesses

Popis výsledku v původním jazyce

This work focuses on the assessment of real fiber and matrix volume ratios of unidirectional fiber composites which can be used for the design of corresponding numerical models on micro-scale. Samples with polished cross-sections were prepared from threecomposite plates and they were analyzed using Scanning electron microscopy (SEM) previously. All plates were manufactured from the same prepreg material using autoclave technology. Each plate consisted of different number of plies. Images of various parts of the composite cross-sections obtained with SEM are analyzed using several image processing techniques programmed in Matlab, its Image Processing Toolbox, and C code. The results of this analysis are the center positions and radii of all fibers within the image. The fiber and matrix volume ratios are determined subsequently and mutually compared for different locations across the plates' thicknesses.
