Photopolymerized composites are widely used from structural materials to biomaterials. We are interested in how photons (light) affect the extent of polymerization (in terms of degree of conversion and/or network structure) in particle-filled composites, and how it influences physical and mechanical properties. Light-curing efficiency can be affected by several factors, including the chemistry and properties of reactive monomers or oligomers as well as filler type, composition, and size distribution. To date, examinations of composite curing efficiency have mainly focused on experimental studies; therefore, if a change in composite design parameters is required, a high cost for time and materials is incurred. Our approach is to develop a numerical simulation suitable for predicting the photo-curing of polymers and optimizing the photopolymerization process.
