Abstract

A comparative analysis of physical and technical characteristics of carbon fibers produced from petroleum mesophase pitches and polyacrylonitrile is carried out. The fields of application of pitch carbon fibers are presented. An explanation of some features of the technologies influencing the achievement of unique properties of carbon pitch fibers is presented. An explanation of the reasons for the lower strength of carbon fibers based on mesophase pitches compared to the strength of carbon fibers based on polyacrylonitrile is given. New fields of application of carbon fibers based on carbon pitches are recommended.
