摘要：

The new CVI + moldless NITE technology combines the advantages of chemical vapor infiltration (CVI) technology and nano-infiltration eutectic transformation (NITE) technology, and is with the potential to prepare long size SiCf / SiC composite cladding tubes. This study has shown that the short-term CVI infiltration can strengthen the fiber preform and keep the inner pores open for the NITE infiltration step; meanwhile, adding polycarbosilane (PCS) to the NITE slurry can effectively reduce the sintering difficulty of the NITE process, so that SiCf / SiC composite tubes can be obtained through hot isostatic pressing method. The maximum density of SiCf / SiC short tubes in this study reaches 2.77g / cm3, and can still be improved. © 2020, Editorial Board of Journal of Nuclear Power Engineering. All right reserved.
