열방호용 코르크계 외부인슈레이션의 가속노화 특성 연구

This paper deals with the accelerating aging charateristic study for the thermal protective cork-based exterior insulator which protect a missile system from aerodynamic loads and heating during flight of missile. We consider the adhesion of cork-based composite on the composite motor case which fabricated by filament winding process. We also consider the importance of the requirement analysis for effective, successful system development under given system conditions. In order to develop the basic requirement analysis for the thermal protective cork-based exterior insulator, an experimental requirement analysis was accomplished, and some experimental results are presented. In result, we calculated the predictive life time of the cork-based exterior insulator.
