The invention discloses a preparation method of a ceramic modified carbon-carbon composite material nose cone, which is characterized by comprising the following steps: placing a carbon fiber preform with a hemispherical front end and a conical rear end in a chemical vapor deposition furnace, repeating chemical vapor deposition of a PyC interface layer and a SiC interface layer to obtain a carbon/carbon blank containing a (PyC/SiC) x interface layer, then the carbon/carbon blank is placed in a chemical vapor deposition furnace for chemical vapor deposition of a carbon matrix to obtain a carbon/carbon porous body, the carbon/carbon porous body is subjected to resin carbon densification to obtain a carbon/carbon composite material, and finally the carbon/carbon composite material is placed in the chemical vapor deposition furnace for chemical vapor deposition of a SiC coating and an HfC coating in sequence. The ceramic modified carbon-carbon composite material nose cone is obtained.

    本发明公开了一种陶瓷改性碳碳复合材料鼻锥的制备方法,其特征在于:将前端呈半球状后端呈圆锥状的碳纤维预制体置于化学气相沉积炉中,重复PyC界面层以及SiC界面层的化学气相沉积,获得含(PyC/SiC)x界面层的碳/碳坯体,再将碳/碳坯体置于化学气相沉积炉中进行化学气相沉积碳基体获得碳/碳多孔体,将碳/碳多孔体进行树脂碳增密获得碳/碳复合材料,最后再将碳/碳复合材料再置于化学气相沉积炉中依次进行SiC涂层以及HfC涂层的化学气相沉积,即获得陶瓷改性碳碳复合材料鼻锥。
