Abstract

Permeability is a key aspect in fibre reinforced composite fabrication. Related problems include the formation of dry spots or voids within composites. These are difficult to solve during composite fabrication particularly with multi-layer woven preforms. To solve these problems, it is important to investigate the relationship between permeability and the microstructure of 3D Multilayer Woven Fabrics (MWFS). In this study, two-dimensional flow experiments with radial liquid injection were carried out to determine the permeability principal values. Based on the experimental results, a basic model for predicting the in-plane permeability of 3D Multilayer Woven Fabrics is established to calculate local permeability values of textiles with different stitch structures. Good agreement was found between the model prediction and the permeability measurements.
