摘要
选用玻璃纤维织物/环氧树脂预浸料以及配套体系材料,采用三步成型的球墨铸铁阴模热压罐固化工艺和专用模具固化蜂窝的方法,研制了机载大曲率、多频段C夹层结构天线罩。经过电性能测试和静力试验,结果表明,该罩体的选材、结构设计和工艺过程是可行的。电性能测试中天线罩最小透波率为84%,全部电参数均满足要求;静力试验中天线罩通过了200%设计载荷的加载,满足结构设计要求。
By applying three steps autoclave cure process with female mold and preimpregnation honeycomb cure process with special mold and selecting glass fabric reinforced epoxy prepreg and corresponding material,a large cur-vature multi-band airborne C-sandwich radome was developed.The results of electric property testing and static testing show the selection of material,structure design and process are feasible.The minimum power transmission efficiency of the radome is 84%;all parameter meet the requirement.The 200% designing load testing was successful;the radome is in agreement with structure designing specifications.
