Compression Resin Transfer Molding (CRTM) is an advanced liquid molding
process for producing continuous fiber-reinforced composite parts in relatively
large dimensions and with high fiber volume fractions. This thesis investigates
this process for the purpose of producing continuous fiber reinforced composites
with particle fillers. In many composites, fillers are used within the resin for
various reasons such as cost reduction and improvement of properties. However,
the presence of fillers in a process involving resin impregnation through a
fibrous medium can result in a composite with non-homogeneous microstructure
and properties. This work aims to model the resin impregnation and particle
filtration during injection and compression stages of the process. For this
purpose, a previously developed particle filtration model is adapted to CRTM.
An appropriate commercial software tool is used for numerical solution after a
survey of available packages. The process is analyzed based on the developed
model for various process scenarios. The results of this study aim to enhance the
understanding of particle-filled resin impregnation and particle filtration
phenomena in the CRTM process and are likely to be used towards designing
optimum process configurations for a desired outcome in the future.
