FRP透波窗性能设计研究

Study on the Performance Design of FRP Wave-transmitting Window

本研究针对FRP透波窗在使用频段范围实现透波率和结构性能的需求,通过材料选择、透波性能设计、仿真分析和结构设计,采用夹层结构形式,制造了FRP透波窗试验件,进行了结构试验和透波试验。试验结果表明,FRP透波窗的结构设计满足承载和密封性要求,同时在1.0GHz~3.0GHz频段范围内的透波率均大于80%,满足透波性要求。实现了对FRP透波窗的承载、密封和透波的设计要求,可以对内部设备的运行状态实现监测。

In order to meet the needs of the FRP wave-transmitting window to achieve wave-transmitting and structural performance in the use of frequency bands,FRP wave-transmitting window specimens were fabricated in the form of sandwich structure through material selection,wave-transmittance design,and structural simulation design,and structural tests and wave transmittance tests were carried out.The test results show that the structural design of the FRP wave-transmitting window meets the requirements of load bearing and sealing,and the transmissivity rate is greater than 80%in the range of 10-30GHz,which meets the requirements.The design requirements of load-bearing,sealing and transmissivity of FRP wave-transmitting window are realized,and the operating state of the internal equipment can be monitored.
