Extraction of void fraction in metal matrix composite using morphological image processing
Lun He, David K. Hsu, John Philip Basart · Advanced Composites Letters · 1994
In continuous fiber reinforced metal matrix composites, the volume fraction of voids in the matrix material is an important parameter for material property characterization. In analyzing a cross-sectional micrograph of such a composite, the presence of fiber images and voids occurring on the perimeter of fibers complicates the determination of void content. This paper describes image processing steps using mathematical morphology for the extraction of void fraction in a composite.
