涂层改性碳纤维复合材料的微波性能研究

Microwave Absorption of Composite with Coating Modified Carbon Fiber

通过对采用化学气相沉积 (CVD)法在碳纤维表面制备SiC涂层、SiC—C共沉积涂层的工艺方法、结构、复合材料电磁参数、复合材料的吸波性能等内容的研究 ,分析了这两种涂层对碳纤维复合材料微波性能的影响 ,探讨其涂层改性在防热、隐身双功能复合材料应用中的可能性。

The CVD process , material microstructure, electromagnetic wave parameter and reflection characteristics of carbon fiber with silicon carbide coating or SiC-C coating and its composites is studied in this paper. The feasibility of applying these fibers to multifunctional composite materials with functions of thermal protection and electromagnetic wave stealth is also discussed.
