Abstract

This paper deals with an alternative multi-functional structures by using grid-stiffened composite structure with excellent bending stiffness and lightweight characteristics which is capable of easy embedding of electrical/electronic circuitry into structure. The enhancement of thermal conduction capability is made by the application of pitch-based carbon fiber. The lightweight radiation spot shielding technique is also proposed for multi-functional structures without conventional housing and the effectiveness of selective radiation shielding is validated through the proton irradiation test.

강성이 우수하고, 경량으로 제작이 가능한 격자강화 복합재 구조체를 다기능 구조체의 기층구조로 적용함으로써, 전기전자회로를 용이하게 내장할 수 있으며 방사차폐 특성을 갖춘 다기능 구조체에 대한 설계 및 제작을 수행하였다. 피치계열 탄소섬유 복합재료의 적용을 통해 열전달특성을 향상시키고, 전자회로의 하우징 구조물이 없어도 우주방사환경에 충분한 내구성을 갖도록 경량 국부 강화 방사차폐 방법을 제안하고, 양성자 조사시험을 통하여 선택적 방사차폐의 효과를 검증하였다.
