摘要Layer-structured interphase, existing between carbon fiber and ultrahigh-temperature ceramics (UHTCs) matrix, is an indispensable component for carbon fiber reinforced UHTCs matrix composites (Cf/UHTCs). For Cf/UHTCs fabricated by reactive melt infiltration (RMI), the interphase inevitably suffers degradation due to the interaction with the reactive melt. Here, Cf/SiC–ZrC–ZrB2composite was fabricated by reactive infiltration of ZrSi2melt into sol-gel prepared Cf/B4C–C preform. (PyC–SiC)2interphase was deposited on the fiber to investigate the degradation mechanism under ZrSi2melt. It was revealed that the degraded interphase exhibited typical features of Zr aggregation and SiC residuals. Moreover, the Zr species diffused across the interphase and formed nanosized ZrC phase inside the fiber. A hybrid mechanisms of chemical reaction and physical melting were proposed to reveal the degradation mechanism according to characterization results and heat conduction calculations. Based on the degradation mechanism, a potential solution to mitigate interphase degradation is also put forward. © 2017 The American Ceramic Society
