Abstract
An improved rocket nozzle liner for solid fuel rockets which is constructed from an inner liner of silicon carbide, a layer of highly anisotropic graphite and an outer shell of heat resistant material. The layer of anisotropic graphite permits thermal expansion of the silicon carbide, thus preventing the build up of thermal stresses and resulting fractures.
