Effect of SiCnws on flexural strength of SiCf/HfC-SiC composites after impact and ablation

SiC nanowires (SiCnws) modified SiCf/HfC-SiC composites were prepared by precursor infiltration and pyrolysis (PIP) and chemical vapor infiltration (CVI) methods. The microstructure, flexural strengths, impact and impact-ablation tests of the composites with and without SiCnws were investigated. The results showed that after introducing SiCnws, not only the retention rate of HfC ceramic produced by PIP was increased obviously, but also the...
