Beschreibung
Zusammenfassung:	The present invention relates to a coating method of a carbon fiber sizing agent, an apparatus thereof, and a composite material manufactured by the same. More particularly, the present invention relates to a method for coating a sizing agent to carbon fiber, wherein solids sizing agent and carbon fiber contact each other. The coating method of the present invention has enhanced workability by increasing rate of fixing fabric width and allowing carbon fibers to have uniform width of tow. Also, the carbon fiber manufactured according to the present invention and the complex material comprising the same have enhanced physical properties. 본 발명은 탄소섬유 사이징제 도포방법, 이의 장치, 및 이들에 의해 제조된 복합재료에 관한 것으로서, 보다 상세히는, 탄소섬유에 사이징제를 도포하는 방법에 있어서, 고형 사이징제와 탄소섬유가 접촉하는 것을 특징으로 하는 탄소섬유 사이징제 도포 방법이다. 본 발명은, 사폭 고정율을 높힘과 동시에 균일한 토우 폭을 갖도록 함으로써, 작업성이 높아짐은 물론, 최종적으로 제조된 탄소섬유 및 이를 포함하는 복합재료의 물성도 향상되는 효과가 있다.
