Abstract

A force-directed algorithm was developed to create representative geometrical models of fibre distributions in Directed Carbon Fibre Preforms (DCFP). Local permeability values were calculated for the preform models depending on the local fibre orientation, distribution and volume fraction. The effect of binder content was incorporated by adjusting the principal permeability values of the meso-scale discontinuous fibre bundles, using corresponding experimental data obtained for unidirectional non-crimp fabrics. The model provides an upper boundary for the permeability of DCFP architectures, where predictions are within one standard deviation of the experimental mean for all architectures studied.
