Abstract

The study has been conducted to know ablation microstructures and characteristics in carbon /phenolic composites. Ablation properties depend on mole fraction of $H_2O$ and $C0_2$ gas which were produced by reaction between propellant and oxidizer. However, the results of this study shown that the ablation also depended on weaving structure, density of fabric, and tow size of carbon fiber. 3K 8HS fabric showed superior ablation resistance to others, 3K twill and 12K 8HS fabric structures.

탄소/페놀릭 복합재의 삭마 미세구조와 특성에 대하여 설명하였다. 삭마현상은 추진제와 산화제 사이의 반응에 의한 수증기와 탄산가스의 몰분율에 의해 좌우된다. 그러나, 이 연구논문은 삭마현상이 탄소섬유의 직조형태, 직조밀도, tow크기에 의해서도 변화될 수 있음을 주사전자현미경, 밀도, 열전도도. 삭마표면등을 통해 설명했다. 3가지의 직조형태중, 3K8HS 직조구조가 3K twill구조나 12K8HS구조보다 우수한 내삭마성을 보임을 설명했다.
