Mathematical models of composite materials prepared by dispersing solid particles of a filler in a liquid polymer matrix

Department: Department of Organic Technology, Faculty of Chemical Technology
Theses supervisor: doc. Ing. Pavel Čapek, CSc.

Annotation

The work is aimed at the mathematical modelling of composite materials, the preparation of which includes the creation of a suspension of solid particles in a liquid mixture of a solvent and a polymer precursor, volume contraction of the suspension caused by evaporating the solvent and by forming a solid polymer matrix. The initial suspension is modelled using the random sequential addition of particles of various shapes. Then, the motion of particles of the filler in the shrinking suspension is simulated. Each model microstructure and the corresponding microstructure of the real composite material sample are characterised using statistical measures and these measures are subsequently compared with each other for the quality of the model to be evaluated. The real microstructures are deduced from digital images of their polished sections that are observed using a scanning electron microscope.
