[0002] Carbon-based composite materials are ultra-high temperature composite materials with carbon fiber fabrics or silicon carbide ceramic fiber fabrics as reinforcement and carbon as the matrix. They possess properties such as lightweight, high strength, high temperature resistance, and corrosion resistance. Carbon-carbon composite materials are composite materials with carbon fiber reinforcement and carbon as the matrix, and their advantages include high temperature resistance, high strength, low density, thermal shock resistance, and corrosion resistance. The most important performance characteristic is that the strength does not decrease at high temperatures.

[0003] The degree of graphitization in carbon-carbon composites is primarily determined using X-ray diffraction and Raman spectroscopy. X-ray diffraction calculates the degree of graphitization by measuring the interlayer spacing of graphite crystals, while Raman spectroscopy assesses the degree of graphitization by analyzing characteristic peaks in the spectrum.12 The detection methods are: X-ray diffraction: measuring the interlayer spacing d002 of graphite crystals and substituting it into the Mering-Maire formula to calculate the degree of graphitization; this method can quantitatively assess the degree of graphitization in carbon materials.13 Raman spectroscopy: assessing the degree of graphitization by analyzing characteristic peaks in the spectrum, such as the intensity ratio of the D peak and the G peak. Raman spectroscopy can provide information about the structural order of carbon materials.
