摘　　要：随着载人航天技术的发展以及综合一体化理念向航天电子领域的延伸,航天电子设备的性能越来越好、功能越来越强,但也对电子模块的质量、体积和散热性能等提出了越来越高的要求。通过分析聚甲基丙烯酰亚胺(PMI)泡沫的特性,设计并制作了采用PMI泡沫和铝合金作夹层的航天电子模块,检测了两种材质夹层的质量和散热性能。结果表明:PMI夹层的质量比铝合金夹层的轻,其散热性能比铝合金夹层的稍差,但对于大部分航天电子模块而言仍是可接受的。Along with both the development of manned space technology and the extension of comprehensive integration idea to aerospace electronic field,the performances of aerospace electronic equipments have got better and better,and their functions have got stronger and stronger.However,mass,dimension and cooling ability requirements for the electronic module will become higher and higher.The aerospace electronic modules in which polymethacrylimide(PMI)foam and aluminum alloy were respectively used as interlayer were designed and made on the basis of analysis on characteristics of PMI foam.The two interlayers were tested for mass and cooling ability.The results indicated that relative to the aluminum alloy interlayer,the PMI interlayer exhibited less mass and slightly worse cooling ability,however,which is acceptable for most of the aerospace electronic modules.
