Methods to Determine the Permeability of Textile Reinforcements
Reinforcing textile permeability is an important material property used to better understand the infiltration phase of Liquid Composite Molding processes. A range of methods exists to determine the permeability of textile porous media all with their respective advantages. In this work, facilities to characterize the saturated and unsaturated in-plane permeability using rectilinear (1D) or radial flow (2D) methods are presented. A comparison of the in-plane permeability results obtained using each test method was carried out, together with the required testing time and material usage. Furthermore, a simulation approach to predict the permeability based on scanned images is presented.
