为探讨分步固化工艺对某中温材料体系天线罩性能的影响,本文对SW-280A/环氧树脂预浸料、FM 73M胶膜和Nomex纸蜂窝组成的中温材料体系层压板及蜂窝夹层结构试样多次固化后的力学性能及电性能进行了研究.结果表明:经一次、二次、三次、四次及五次固化后,力学性能及电性能变化幅度不大,无明显的下降趋势,说明多次固化未对该中温材料体系的力学性能及电性能造成影响.材料体系天线罩的制造可以采用分步固化工艺,分步固化工艺对其力学和电性能不会产生影响.
To explore the effect of curing by steps on properties of radome made of moderate temperature material system, the mechanical and electromagnetic properties of laminate and honeycomb sandwich spesimen after made of moderate temperature material system including SW-280A/epoxy prepreg, FM 73M film and Nomex honeycomb multicuring was discussed in this paper. The results show that there are small changes in mechanical properties and electric properties and no significant downward trend after first, second, third, fourth and fifth curing. This implied that curing by steps doesn't have affect the mechanical and electromagnetic properties of the moderate temperature material system. So radomes made of the material system can be manufactured with curing by steps and curing by steps does not affect the mechanical and electromagnetic properties of radomes.
