Casting법에 의해 제조된 탄소섬유/알루미늄 복합재료에 관한 연구

다국어 초록 (Multilingual Abstract)

Has a long lifespan and low energy consumption of LED is received attention by eco-friendly light source. But, LED is have problems that light output decline and lifespan decrease at elevated temperatures. In addition, Coefficient of thermal expansion(CTE) gap of between substrate and heat sink showed increasing trend with increasing thermal conductivities. Accordingly, between substrate and heat sink is may occur crack. So, the new material with high thermal conductivities and low coefficient of thermal expansion is required. In this study, carbon fiber with high thermal conductivities and low thermal expansivity reinforced Al composites were manufactured using a casting process, and Carbon fiber/aluminum (CF/Al) composites were successfully fabricated without pressure casting using wettability modification of carbon fiber. The wettability of liquid aluminum on carbon fibers was enhanced through electroless plating of copper on carbon fibers.
