We proposed an experimental device and a numerical scheme to simultaneously identify the saturated permeability and the compressibility of preform in the through-thickness direction. By a single compression of the preform under a specified liquid inlet condition, we can obtain the permeability and the compressibility as a function of fiber volume fraction.
