Simulation of the Gas Evolution Process and Filtration during Preparation of Ipresscon® Carbon Frames

An important distinctive feature during the preparation of products from an Ipresscon® carbon–carbon composite is the formation of carbon fibers from Oxypan® oxidized polyacrylonitrile fibers. The polymer fibers are transformed into carbon ones with gas evolution and stresses during high-temperature heat treatment under pressure. A model of a porous skeleton, in which pores are replaced with disk-shaped gaps, is proposed. High-temperature experimental data and theoretical calculations resulting in Ipresscon® high-quality products are reported.
