Carbon/carbon-silicon carbide gradient composite material flat plate as well as preparation method and application thereof
The invention relates to a carbon/carbon-silicon carbide gradient composite plate and a preparation method and application thereof, and belongs to the technical field of powder metallurgy. The preparation method comprises the following steps: preparing a carbon/carbon-silicon carbide gradient composite material flat plate from a silicon-containing carbon fiber composite preform through a chemical vapor co-deposition densification process and a chemical vapor co-deposition coating process; the silicon-containing carbon fiber composite flat plate prefabricated member is prepared by spraying or impregnating a carbon fiber prefabricated member with silicon-containing precursor resin and/or a silicon-containing organic binder. According to the prepared carbon/carbon-silicon carbide gradient composite material flat plate, gradient is formed in the thickness direction from inside to outside, the reaction speed of the surface of the flat plate and oxygen at the high temperature is reduced, the bonding problem of metal and a carrier plate during powder metallurgy sintering is fundamentally solved, and the service life of the flat plate is effectively prolonged.
本申请涉及一种炭/炭‑碳化硅梯度复合材料平板及其制备方法与应用，属于粉末冶金技术领域。其制备方法包括：含硅炭纤维复合预制件经化学气相共沉积增密工艺、化学气相共沉积涂层工艺制得炭/炭‑碳化硅梯度复合材料平板；所述含硅炭纤维复合平板预制件由炭纤维预制件喷淋或浸渍含硅前驱体的树脂和/或含硅有机粘结剂制得。本发明制得的炭/炭‑碳化硅梯度复合材料平板，由内而外、厚度方向形成梯度，降低了高温下平板表面与氧的反应速度，从根本上解决粉末冶金烧结时金属与载板的粘接问题，有效提高平板的使用寿命。
