Modification of the Fiber-Matrix Interface in the Carbon Fiber Reinforced ZrB₂- Based Ultra-High Temperature Ceramic Composites

Abstract:

Carbon fiber reinforced ultra-high temperature ceramic composite (C_f/UHTC) is a typical structural material currently used for aero-engine parts, hot gas valve parts, and thermal protection systems. However, for C_f/UHTC, one of the key issues is that the carbon fibers may be prone to react with the matrix of UHTC during the high-temperature sintering process. This paper mainly focused on restraining the serious fiber-matrix interfacial reaction. The carbon fiber reinforced ZrB₂-based composite (C_f/ZrB₂-based composite) was selected as the research material in the current work. Some processing methods were adopted to restrain the fiber-matrix interfacial reaction. Microstructure analysis, element distribution, and phase composition were characterized by using scanning electron microscope (SEM), energy dispersive spectrometer (EDS) and X-ray diffraction (XRD), respectively. The results indicated that the matrix/fiber interfacial reaction in the C_f/ZrB₂-based composite was closely related to the processing methods.
