3D imaging and analysis of fibrous filter sheets using X-ray microtomography and image analysis

ABSTRACT

This study analyzes filter material that is used in many applications such as filtration of air, fuel, chemicals, and beverages. “In this study micro-CT is used for the 3D visualisation and analysis of fibrous filter sheets with a thickness ranging from 40 to 90 μm made from different fibre materials and produced using different processes. Fibres with different densities are visible in micro-CT images as gradients of grey levels or intensities, and can be straightforwardly segmented using thresholding. Image analysis is used to quantify the pore morphology.” This study demonstrates how micro-CT was used to determine the true thickness of thin fibrous filters, as well as how quantitative information on porosity, pore size distribution, and pore interconnectedness was obtained from the scans..

Machine Learning-based Single Fiber Extraction from Micro-CT Scans with GeoDict

ABSTRACT

This study focuses on micro-CT images of fibrous structures that often have a complex shape that spans a large portion of the scanning domain. These fibrous structures and their fibers are present in many microstructures, including non-woven filter media used for filtration. “Spatial distribution, orientation, length, curvature and center line of fibers in materials like these are essential characteristics required in modern material design.” The researchers offer a machine learning-based algorithm for the identification and extraction of individual fibers in segmented 3D images in order to more completely characterize them.

Microcomputed tomography–based characterization of advanced materials: a review

ABSTRACT

Micro-CT is helpful in the design of efficient filters and in the improvement of filter models for more accurate simulations. Using micro-CT, changes in porosity through the whole thickness of a fibrous filter can be seen and the structure-dependent behavior of deposits can be observed. The effects of microstructure on aerosol deposition in high efficiency particulate air (HEPA) filters can be studied as well as the effects of filtration velocity on clogging. This review “summarizes characteristic materials science micro-CT applications in bioinspired materials, structural materials, porous natural materials, energy storage, energy conversion, and filtration.”
