等温化学气相渗透（ＩＣＶＩ）是制备高性能碳／碳复合材料最为重要、应用最为广泛的技术手段。本文通过研究ＩＣＶＩ制备单向碳／碳复合材料的致密化过程，分析了单向碳／碳复合材料致密化的特点，并对致密化均匀性问题进行了初步探索，为优化工艺、提高致密化效率，提供一定的借鉴。
Isothermal chemical vapor infiltration (ICVI) is the most important and widely used technique for preparing high-performance carbon / carbon composites. In this paper, the densification process of unidirectional carbon / carbon composites prepared by ICVI was studied. The characteristics of densification of unidirectional carbon / carbon composites were analyzed. The problems of densification uniformity were also explored. In order to optimize the process and improve the densification Efficiency, provide some reference.
