| 摘 要： | 研究了自然气象条件下单层碳纤维吸波涂料的静态吸波性能随时问变化的规律。通过人工加速老化试验模拟自然气象分周期作用于吸波材料试样，然后测量其电磁参数与反射率，并对实验数据进行处理，结合由电磁参数计算反射率模型的理论推导，最终建立了试样的反射率随时间变化模型，并依此预测此涂料的使用寿命，为确定其在隐身飞行器上的使用与维护时限提供依据。

| Abstract: | The static electromagnetic wave absorbing performance of the RAM which consists of single coat of carbon fiber in the natural environment was studied. Artificial aging experiment was performed on test board, then the electromagnetic parameters and reflectivity of it were measured, combing with the derivation of the model in which the reflectivity can be calculated with electromagnetic parameters, to build the model of reflectivity changing over time. It is used to forecast the natural life of the RAM coats used on the surface of stealth aircrafts. |
