Composite materials based on coal tar pitch

Abstract

Coal tar pitch is a unique product with a rich set of properties, among which are polymeric ones. Modification of coal tar pitches provides a wide opportunity to adjust and change their properties. This opens a new direction - the use of coal tar pitch chemical potential for creating the disperse-filled compositional polymeric materials. The obtained pitch composite has relatively high mechanical properties and thermal stability. The obtained material for all parameters can be attributed to the hard-burning polymer composite what gives it a cogent advantage comparably to thermoplastic polymers. Tests of modified coal tar pitch as a polymer matrix showed that it can successfully compete with classical polymers in order to create compositional materials.
