Thin-wall ceramic-based composite material with heat conduction function and preparation method of thin-wall ceramic-based composite material
The invention relates to a thin-wall ceramic matrix composite material with a heat conduction function and a preparation method thereof. The thin-wall ceramic-based composite material is prepared by adopting a PAN-based fiber spread band and a mesophase pitch-based fiber spread band to be mixed and woven into a thin-wall preform and combining CVI and PIP matrix densification processes. The method comprises the following steps: firstly, preparing a PAN-based fiber spread band and mesophase pitch-based fiber spread band mixed-woven thin-wall preform by adopting a 2.5 D weaving technology, then, carrying out pyrolytic carbon interface layer deposition on the surface of carbon fiber by adopting a CVI (Chemical Vapor Infiltration) process, and then, carrying out SiC ceramic matrix densification on the preform by adopting CVI and PIP processes respectively. The prepared thin-wall ceramic-based composite material with the heat dredging function is very thin (smaller than or equal to 1 mm) and can meet the development requirements of light sandwich structure panels of aircrafts.
本发明涉及一种具有热疏导功能的薄壁陶瓷基复合材料及其制备方法。所述薄壁陶瓷基复合材料采用PAN基纤维展宽带与中间相沥青基纤维展宽带混编薄壁预制体，结合CVI与PIP基体致密化工艺制备得到。所述方法首先采用2.5D编织技术制备PAN基纤维展宽带与中间相沥青基纤维展宽带混编薄壁预制体，然后采用CVI工艺在碳纤维表面进行热解碳界面层沉积，之后分别采用CVI与PIP工艺对其进行SiC陶瓷基体致密化。本发明所制备的具有热疏导功能的薄壁陶瓷基复合材料厚度非常薄(≤1mm)，可满足飞行器轻量化夹层结构面板研制需求。
