改进的由陶瓷基体复合材料制成的多层管、产生的核燃料包壳及相关生产方法
摘要：
本发明涉及一种多层管状部件（1），包括：形成金属管状主体（3）的金属层和覆盖所述金属管状主体的陶瓷基体复合材料的两个层，其中陶瓷基体复合材料的两个层中的一个层覆盖金属管状主体的内表面以形成内部管状主体（4），而陶瓷基体复合材料的两个层中的另一个层覆盖金属管状主体的外表面以形成外部管状主体（2），金属管状主体从而被夹入在内部管状主体和外部管状主体之间。金属管状主体是由金属或金属合金制成。而且，金属管状主体的平均厚度小于内部管状主体的平均厚度和外部管状主体的平均厚度。这种部件可具体用于生产核燃料包壳。
摘要（英）：

The invention relates to a multilayer tubular part (1) comprising: a metal layer forming a metal tubular body (3); and two layers of ceramic-matrix composite material covering the metal tubular body, in which one of the two layers of ceramic-matrix composite material covers the internal surface of the metal tubular body in order to form an internal tubular body (4), while the other of the two layers of ceramic-matrix composite material covers the external surface of the metal tubular body in order to form an external tubular body (2), the metal tubular body thus being sandwiched between the internal and external tubular bodies. The metal tubular body is made from metal or metal alloy. Furthermore, the metal tubular body has an average thickness less than the average thicknesses of the internal and external tubular bodies. Such a part can in particular be used to produce nuclear fuel cladding.
