摘要:

超高溫陶瓷（UHTCs）因在高超聲速飛行器熱防護領域的巨大應用前景而備受關注，而脆性大、燒結成型困難是制約UHTCs廣泛應用的實質問題。將碳纖維與UHTCs復合獲得碳纖維增強超高溫陶瓷基復合材料（Cf/UHTCs）是克服這一問題的可靠方案。近10年來，我國在Cf/UHTCs工程應用方面獲得了重大突破，取得了一系列具有世界先進水平的應用成果。然而，由于Cf/UHTCs制備過程復雜，服役環境苛刻（＞2000 ℃，＞5 Ma氣流沖刷），在結構演化、性能機理等方面仍存在一些關鍵科學問題亟需明確。綜述了Cf/UHTCs在基體改性、氧化燒蝕機理、高溫力學行為等方面的研究進展，并結合本團隊的研究工作對Cf/UHTCs的研究趨勢進行了總結和展望，旨在為進一步推動Cf/UHTCs的研究和發展提供參考。

Abstract:

Ultra-high temperature ceramics (UHTCs) have received great attention due to their application potentials in the thermal protection system of hypersonic vehicles. The major problems that restrict the wide application of UHTCs are high brittleness and difficulty to be sintered. Introduction of carbon fiber into UHTCs to obtain fiber reinforced UHTCs (Cf/UHTCs) is an effective solution to these problems. In the past 10 years, our country has made major breakthroughs in the engineering application of Cf/UHTCs and obtained a series of world�瞔lass achievements. However, because of the complicated preparation process and harsh service environment (>2000 ℃, >5 Ma airflow scouring), Cf/UHTCs still exist several critical scientific issues need to be clarified, especially in terms of structural evolution and performance mechanisms. reviews The research progress on matrix modification, oxidation-ablation mechanism and high-temperature mechanical properties of Cf/UHTCs was reviewed. Also, the future research trends of Cf/UHTCs based on the recent research results of our group were summarized and prospected. This paper provides a reference for further research and development of Cf/UHTCs.
