In-Plane Permeability Model of 0°/90° Non-crimp Fabrics in Resin Transfer Molding

Abstract

Permeabilities one of the key parameters controlling infiltration of the fabrics in Resin Transfer Molding. In this paper, the in-plane permeability of 0°/90° non-crimp fabrics was modeled as a function of geometrical yarn parameters. The unit cell was decomposed into four different zones of characteristic yarn arrangement. The overall permeability was then modeled as a mixture of permeabilities of different zones with the electrical resistance analogy. With the predictive model, the influence of yarn parameters was deeply researched. And permeability predictions show satisfactory agreement with experimental data obtained byin-plane permeability measurements.
