Method on measuring fibre permeabilities in resin transfer molding

This paper introduces the processes and characterizations of the resin transfer molding briefly. The governing equations of resin flow are presented on the base of Darcy's law. By the transformation of the anisotropic system and its equivalent isotropic system, a novel method is proposed for measuring the in-plane permeabilities of the anisotropic fibre preform. The in-plane permeabilities of the orthotropic fabric media are calculated from fluid and fibre properties together with data from the mold filling experiment, and good agreement is found between the results and the quoted datas.
