초록

복합재 항공기 동체의 낙뢰손상방지를 목적으로 탄소섬듐-주석 산화물(ITO) 나노입자를 코팅함으로써 탄소섬유강화플라스틱(CFRP) 복합재료의 전기전도도를 향상하였다. 탄소섬유에 코팅된 ITO 나노입자는 10~40%의 농도로 콜로이드 상태에서 분사되었다. CFRP의 전기전도도는 코팅 후 3배 이상 증가하였으며 현재 B-787 복합재 항공기 동체에 사용 중인 기술인 금속메쉬를 CFRP 외층에 매몰한 경우보다도 높은 전기전도도를 얻을 수 있었으며, 나노입자 코팅으로 섬유-기지 계면에 미지는 악영향은 발견되지 않았다. 모의 낙뢰에 의한 손상영역은 각각 다른 처리를 한 재료와 조건에 따라 초음파 C-scan 이미지로 확인하였다. ITO 40% 코팅 시편의 경우 전기전도도는 B-787 샘플의 경우보다 높았지만 낙뢰에 의한 손상영역의 크기는 거의 비슷한 수준이었다.

The electrical conductivity of carbon-fiber reinforced plastics (CFRP's) has been improved by indium-tin oxide (ITO) nano-particle coating on carbon fibers for the purpose of lightning strike protection of composite fuselage skins. ITO nano-particles were coated on the surface of carbon fibers by spraying the colloidal suspension with 10~40% ITO content. The electrical conductivity of the CFRP has been increased more than three times after ITO coating, comparable to or higher than that of B-787 composite fuselage skins with metal wire-meshes on the outer surface, without sacrificing the tensile property due to the existence of nano-particles at fiber-matrix interface. The damage area by the simulated lightning strike was also verified for different materials and conditions by using ultrasonic C-scan image. As the electrical conductivity of 40% nano-ITO coated sample surpass that of the B-787 sample, the damage area by lightning strike also appeared comparable to that of the materials currently employed for composite fuselage construction.
