SEMINAR ABSTRACT:One of the most efficient methods to produce structural profiles of polymer composite materials is a pultrusion process. Pultrusion is a process where a continuous reinforcement is pulled through an impregnation bath containing thermoset resin and then fed into a heated forming die determining the geometry of pultruded profile cross section, where resin cure takes place. Pultrusion products are widely used in the various industries: construction, aerospace, automotive, energy, agriculture, sports, tourism. The presentation will provide an overview of the history, the row materials, technological stages, manufactured product types and their properties. It will also consider methods of mathematical simulation of the pultrusion process by using of methods of continuum mechanics. Examples of technological regimes optimization based on modeling the temperature fields, the degree of polymerization, and the stress-strain state will be given. |
SPEAKER INTRODUCTION:Dr. Alexander Safonov graduated from the Faculty of Mechanics and Mathematics of MSU in 2002 and obtained his Candidate of Science degree at Research Institute for Machine Science named after A.A.Blagonravov of RAS in 2006. Alexander has been working in the academic and engineering fields of mechanics of composite materials for more than 15 years. Alexander joined Skoltech as a Team Leader in 2013. Alexander supervised implementation of industrial research contracts. The aim of the projects was to develop mathematical modeling methods for the technological process of manufacturing large-size composite aviation structures. As Leading Research Scientist at CDM² Alexander conducts of research and industrial projects with CJSC AeroComposit, Central Aerohydrodynamic Institute and University Partners. Alexander participates in the development of educational courses in Continuum Mechanics and Manufacturing Processes. |
