초록

본 연구에서는 탄소재료의 우수한 열적 특성을 이용하여 에폭시 수지의 열전도도 특성을 향상시키기 위해 Pitch 탄화유리섬유를 제조하고 산처리 기능화 방법을 수행하여 형태학적, 기계적, 및 열전도 특성을 관찰하였다. 그 결과, 산처리 기능화된 Pitch 탄화유리섬유는 에폭시 수지 내에서 분산성 및 계면결합력이 향상됨에 따라 기계적 물성 및 열전도 특성이 증가함을 확인하였다. 특히, Pitch 탄화유리섬유 복합재료 내의 Pitch 탄화유리섬유의 함량이 증가함에 따라 기계적 물성 및 열전도 특성이 증가하여, 탄소섬유 복합재료보다 기계적 물성은 10%, 열전도 특성은 150% 향상됨을 확인하였다. 따라서, 본 연구에서 제조된 Pitch 탄화유리섬유의 우수한 구조배향성 및 계면결합력은 에폭시수지내의 분산성을 향상시키고 열전도성 경로를 형성하여 에폭시수지의 우수한 기계적 및 열전도 특성에 영향을 미치는 것으로 판단된다.

In this work, pitch-carbonized glass fibers were prepared for reinforcement of composites. The influence of acid functionalization of the fibers on the morphological, mechanical, and thermal properties of fiber-reinforced epoxy matrix composites was investigated. The acid functionalization of the fibers led to 10 and 150% increases in the mechanical and thermal properties, respectively, as compared to carbon fiber-reinforced composites. This can be attributed to the superior orientation of fiber structures and good interfacial interactions between fillers and epoxy matrix, resulting in enhanced degree of dispersion and formation of thermally conductive paths in the functionalized composites.
