通過向碳/碳復(fù)合材料基體中摻雜難熔金屬化合物，研制出了一類集碳/碳材料優(yōu)異的高溫力學(xué)、熱物理性能和超高溫陶瓷材料非燒蝕性能于一體的超高溫本體抗氧化碳/碳復(fù)合材料。攻克了難熔金屬化合物在復(fù)合材料中分布以及組元與碳纖維反應(yīng)控制關(guān)鍵技術(shù)，提高了復(fù)合材料的力學(xué)性能。靜態(tài)和動態(tài)高頻等離子風(fēng)洞超高溫本體抗氧化試驗(yàn)表明，在駐點(diǎn)溫度達(dá)到2 500 ℃，600 s燒蝕后燒蝕量僅為碳/碳復(fù)合材料的1/5，給出了超高溫本體抗氧化碳/碳復(fù)合材料氧化燒蝕抑制機(jī)理。
- Abstract:
-
The ultra high temperature matrix antioxidation carbon/carbon composites（UHT C/C）, which integrate with carbon/carbon composites and ultrahigh temperature ceramics, were prepared via introducing of refractory compounds. Through microstructure controlling, the mechanical properties of composites were obviously increased while the reactivity was restrained between refractory compounds and carbon at high temperature. The oxidation resistant performance of these composites was tested in static state and highfrequency plasma wind tunnel, Results showed that the introduction of refractory compounds significantly increased the oxidation resistance performance of composites, the ablation length was under 2 mm after 600 seconds of the test over 2 500 ℃. And ultra high temperature matrix antioxidation mechanism of the composites was found.
