摘　　要：第三代SiC纤维具有近化学计量比的元素组成和高结晶致密的特性,与第一、第二代SiC纤维相比,在耐高温、抗氧化、抗蠕变及抗辐射等性能上均有明显的提升,因此在工程应用上尤其在核能领域拥有更明显的优势和更广阔的前景。本文对第三代SiC纤维的制备工艺、性能特点进行了介绍和比较,综述了第三代SiC纤维在核能领域的应用,并对其发展前景进行了展望。The third generation SiC fibers have near-stoichiometric composition and polycrystallinity with high density. Compared with the first and second generations, they have obvious improvements in heat-resistance, creep-resistance and radiation-resistance. Accordingly, they have more advantages and broader prospects in engineering applications, especially in the nuclear field. In this paper, the fabrication and performance characteristics of the third generation SiC fibers are introduced and compared. The applications of the third generation SiC fibers in the field of nuclear energy are reviewed, and the development prospects are prospected.
