Abstract

Resin impregnation of carbon materials was affected by surface of carbon materials. The surface of carbon materials with coupling treatment improved comparability and wettability with resin, and that increased impregnation efficiency and properties of carbon materials. As a results of FT-IR, The silanol was coated on carbon surface with one layer. Coupling treatment of carbon materials increased impregnation efficiency, which improved porosity, mechanical strength, density and friction behavior.

탄소재의 수지함침은 탄소재 표면 상태에 영향을 받는다. Coupling처리에 의한 탄소재 표면처리는 수지와의 호환성과 젖음성을 개선시켜 함침효율과 물성을 향상시킨다. 본 연구에서는 표면개질을 위해 탄소재를 실란 coupling 처리하였다. FT-IR 관찰결과 실라놀은 탄소재 표면에 단층으로 코팅되었음을 확인하였다. 탄소재의 coupling 처리는 함침효율을 향상시켜 기공율, 기계적 강도, 밀도, 마찰거동이 개선되었다.
