Software for the research of microfibrilar composites

Abstract

The first chapter of the monograph describes the theoretical basis of obtaining microfibrils by processing melts of polymer mixtures. The experimentally confirmed mechanism of the phenomenon, necessary and sufficient conditions for its implementation, and ways of controlling this process are given. The second section contains programs developed by the authors for mathematical modeling of the influence of various parameters (the content of components in the mixture, the ratio of viscoelastic properties of polymers, the value of interfacial tension, the angle of entry of a drop into the capillary, etc.) on the morphology of the system and for calculating the dimensional characteristics of microfibrils. Of particular interest is the created computer animation model, which adequately reflects the real processes of deformation of drops of one polymer in the mass of another under the flow of melts of mixtures in the entrance zone of the forming hole and allows to visually demonstrate the process of formation of microfibrillar morphology. Monograph is intended for a wide range of teachers, scientists, post-graduate students, masters and students majoring in computer science and chemical technologies of specialized higher educational institutions, engineering and technical workers in the computer and chemical industries.
