초록

본 논문에서는 CFRP로 구성된 항공 드론 프레임의 수직 낙하충격으로 인한 CFRP적층구조에서의 파손거동을 해석적 연구를 통해 파악하였다. 기존 플라스틱 재료와 달리 CFRP는 섬유로 구성되어 파손거동이 복잡하다. 따라서 이에 대한 실험에 앞서 해석적 연구를 통해 선행 연구가 중요하다. 본 연구의 결과로서 기존의 연구모델과 비교하여 보면, 같은 조건으로 중앙 노치구멍을 가진 적층된 CFRP 드론 프레임의 해석모델에서 가해진 응력의 값이 크게 줄어듬을 볼 수 있었다. 본 연구 결과를 토대로 드론프레임의 노치구멍에 관한 기반데이터를 융합기술에 접목함으로서 그 미적인 감각을 나타낼 수 있다.
