Error assessment in permeability measurement using radial flow method

Abstract

Permeability values measured on textile reinforcements with different methods or different test set-ups can differ significantly from each other. Even measurements preformed on the same test set-up can have a substantial scatter of measured permeability values. This paper discusses the sources of possible measurement errors for a radial flow set-up and their influence on the measured permeability results. Suggestions are given to improve the reliability of permeability measurements.
