Abstract The distribution of filler particles during infiltration of fiber preforms with particle-filled preceramic polymers has a crucial effect on the degree of cure and the properties of the end product. A two-dimensional accumulation-detachment filtration model is incorporated into a two-dimensional flow solution technique to predict the volume fraction distribution of the filler particles during the impregnation/resin transfer molding (I/RTM) of particle filled preceramic polymers into fiber preforms. The results of the filtration model and the main flow solution are coupled. In addition, the non-linear relations between the particle volume fraction distribution, the flow properties and the mold geometry are investigated.
