Abstract

This report discusses the impregnation of carbon and graphite materials with carbonaceous liquids and the subsequent heat treatment required to convert these liquids to coke and graphite in the pores of the base materials. The purpose of the impregnation process is to increase the strength and density and decrease the porosity of the finished articles. Impregnation procedures, the natures of the impregnants, and base stock structure affect the physical properties of impregnated graphite. Mercury porosimetry is used to define the pore structure of the bodies to be impregnated and aid in selection of impregnant and impregnating procedure. The physical properties of the impregnated graphite are related to the performance of nozzle inserts in a sub-scale solid propellant rocket motor.
