This analysis demonstrates how filler particle distribution affects volume fraction in fiber preforms, implying that understanding flow properties is crucial for outcomes.
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.
