Experimental studies by a number of researchers have shown that a carbon-rich interface is formed between Nicalon' Sic fibers and several different glass and glass-ceramic mahix materials. This carbon layer is believed to play an important role in the outstanding mechanical properties of these composites. A basic understanding of the chemical interactions between the matrix and fibers is necessary to model interface evolution and stability and to predict other possible composite systems. Herein, calculations of thermodynamic equilibria between silica and doped silicate glass matrices and SiC fiber systems provide a fundamental description of this carbon layer formation. Transport mechanisms for the interface constituents contribute to the modeling of the growth of the carbon interphase.
