The invention discloses a preparation method of a stealth airfoil component, the stealth airfoil component is composed of a dielectric layer material, a wave-absorbing functional material and a shielding bottom layer material, and the wave-absorbing functional material is rapidly detected before the stealth airfoil component is manufactured and formed. A device used for testing comprises a reflectivity field measuring instrument, a standard reference medium layer plate and a shielding bottom plate, and the testing is carried out according to the following steps that a wave-absorbing functional material, the standard reference medium plate and the shielding bottom plate form a multi-layer structure, and the layering sequence of the multi-layer structure is required to be consistent with the actual layering sequence of an invisible wing surface component; the standard reference dielectric plate is made of a dielectric layer material, and the thickness of the standard reference dielectric plate is consistent with the designed thickness of the dielectric layer material in an actual laying layer. A reflectivity field measuring instrument is pressed on the outer surface of the multi-layer composite structure for reflectivity testing, and whether the stealth performance of the wave-absorbing functional material used for forming the stealth wing surface part reaches an expected index or not is judged according to whether the test result R reaches the standard or not.

    本发明公开了一种隐身翼面部件制备方法,隐身翼面部件由介质层材料和吸波功能材料和屏蔽底层材料组成,隐身翼面部件制造成型前对吸波功能材料进行快速检测。该测试所用装置包括反射率现场测量仪,标准参考介质层板和屏蔽底板组成,测试按如下步骤进行:吸波功能材料与标准参考介质板和屏蔽底板一起组成多层结构,要求其铺层顺序与隐身翼面部件实际铺层顺序一致。标准参考介质板采用介质层材料制备,且厚度与实际铺层中介质层材料的设计厚度一致。通过反射率现场测量仪压紧于多层组合结构的外表面进行反射率测试,根据测试结果R是否达标判定吸波功能材料用于隐身翼面部件成型后的隐身性能能否达到预期指标。
