C/HfB2-HfC-Cu composite material and preparation method thereof
The invention relates to a C/HfB2-HfC-Cu composite material and a preparation method thereof. The C/HfB2-HfC-Cu composite material is prepared by a method of combining precursor infiltration pyrolysis (PIP) and reactive infiltration (RMI). The method comprises the following steps: firstly depositing a pyrolytic carbon interface layer on the fiber surface of a carbon fiber preform, then preparing a porous low-density C/C-B4C base material by adopting a PIP process, and then carrying out reactive infiltration on the porous low-density C/C-B4C base material by adopting a hafnium-copper alloy infiltrating agent on the basis of the porous low-density C/C-B4C base material to obtain the C/HfB2-HfC-Cu composite material. The preparation temperature is low, and the prepared composite material has excellent oxidation ablation resistance.
本发明涉及一种C/HfB2‑HfC‑Cu复合材料及其制备方法，通过前驱体浸渍裂解(PIP)与反应熔渗(RMI)相结合的方法制备C/HfB2‑HfC‑Cu复合材料。所述方法首先在碳纤维预制体纤维表面沉积热解碳界面层，然后采用PIP工艺制备多孔低密度C/C‑B4C基材，之后在其基础上采用铪铜合金渗剂对多孔低密度C/C‑B4C基材进行反应熔渗，得到C/HfB2‑HfC‑Cu复合材料。本发明制备温度低，制备得到的复合材料具有优异的抗氧化烧蚀性能。
