초록

본 연구는 탄소섬유강화플라스틱(CFRP) 복합재료로 제작된 항공기 등 구조물의 낙뢰에 의한 손상을 방지하기 위하여 전도성 은나노입자를 탄소섬유에 코팅한 후 에폭시 수지로 함침함으로써 CFRP의 전기전도도를 향상시키는 방법에 대한 것이다. 전기전도도 측정은 4점측정법을 통해 저항값을 측정하고 이를 전기전도도 값으로 변환하였으며, 나노입자 코팅 상태와 전기전도도의 변화를 관찰하였다. 또한 SEM과 EDS를 통해 탄소섬유 표면에 코팅된 은나노입자의 존재와 전기적 네트워크가 형성된 것을 확인하였다. 결과로써 일반 CFRP의 약 3배 이상의 전기전도도를 얻을 수 있었다.

The improvement of electrical conductivity of carbon-fiber reinforced plastics (CFRP) has been investigated by silver nano-particles coating for the purpose of lightning strike protection. Silver nano-particles in colloid were sprayed on the surface of carbon fibers, which were then impregnated by epoxy resin to form a CFRP specimen. Electrical resistance was measured by contact resistance meter which utilize the principles of the AC 4-terminal method. Electrical resistance value was then converted to electrical conductivity. The coated silver nano-particles on the carbon fibers were verified by SEM and EDS. The electrical conductivity was increased by three times of the ordinary CFRP.
