Thick composite materials are used as liners in rocket nozzles, due to its structural strength, low density and very high thermal insulation property. Carbon fiber and Silica fiber based composite structures are used in the nozzles of large solid rocket motors. Since these are multiple layer structures, the commonly observed defects are delaminations, lack of adhesive material, porosity between layers etc. X-ray radiography techniques are generally used for the NDE of these composite nozzle liners. In this paper the theoretical modeling of radiographic images are carried out to provide input for interpretation of radiographs in silica phenolic composite nozzle liners. Details of software developed in C++ language and its application to solve specific problems are discussed here.
