This study focuses on the understanding and modeling of the physical phenomena occurring in the heated surface of Silica Phenolic (hereafter referred as SiFRP) under exposure to high temperature gases when applied to liquid rocket engine (LRE) combustor. Although the understanding and modeling of the phenomena is supposed to be essential in designing LRE combustor, the works done in this fields are seldom seen in open literatures. When we look at the inner surface of SiFRP combustor of LRE after ground firing tests, the signs of white streak, melting and recession are sometimes observed. In this research, the experimental characterization activities on the SiFRP surface phenomena are conducted, based on the various optical measurements (digital camera, SEM (scanning electron microscope), XRF (X-ray fluorescence), spectral reflectivity (wavelength: 400-700 nm)) for the heated samples, namely, the ones from arcjet heating tests under Air or N2 stream conditions or the ones from SiFRP combustor after LRE.
