High-temperature-resistant infrared/radar compatible stealth ceramic-based composite material and preparation method thereof
The invention discloses a high-temperature-resistant infrared/radar compatible stealth ceramic-based composite material and a preparation method thereof, and relates to the technical field of wave-absorbing materials. Comprising a ceramic-based composite layer and a plurality of composite film units which are arranged on the ceramic-based composite layer in a matrix mode. The ceramic-based composite layer comprises a fiber preform and a ceramic matrix formed on the fiber preform through a chemical vapor deposition method or permeation cracking; each composite film unit includes a low emissivity component and a doped component. The composite material provided by the invention can be used in a high-temperature environment of 1000 DEG C, has low infrared emissivity and good radar wave absorption capacity, has certain bearing capacity, and is simple in structure and easy to prepare.
本发明公开了一种耐高温的红外/雷达兼容隐身陶瓷基复合材料及其制备方法，涉及吸波材料技术领域。包括陶瓷基复合层以及所述陶瓷基复合层上设置有矩阵式排布的多个复合薄膜单元；所述陶瓷基复合层包括纤维预制体以及所述纤维预制体上通过化学气相沉积法或渗透裂解而成陶瓷基体；每个复合薄膜单元均包括低发射率组分和掺杂组分。本发明提供的复合材料能够在1000℃的高温环境中使用，兼具低红外发射率和良好的雷达波吸收能力，同时具备一定的承载能力，且结构简单、易于制备。
