dc.description.abstract본 연구는 유리중공입자 표면의 거칠기가 유리중공입자-에폭시 syntactic foam의 열전도도에 어떠한 영향을 미치는지 알아보기 위하여 진행 되었다. 유리중공입자의 표면 거칠기를 변화시키기 위하여 염기성 용액을 이용한 표면 처리를 실시 하였다. 그 후, 표면 처리 완료된 입자를 사용하여 55 ~ 80% 의 유리중공입자 부피비를 가지는 syntactic foam을 제작하였고, 그 열전도도를 측정하여 표면처리가 되지 않은 입자를 사용한 syntactic foam의 열전도도와 비교하였다. 그 결과, 표면처리를 실시 한 유리중공입자롤 사용하여 제작 한 syntactic foam의 열전도도가 기존 입자를 사용 한 경우와 비교해 소폭 감소되는 것이 확인 되었다.-
dc.description.abstractTo investigate the effect of the surface roughness of glass-microsphere on thermal conductivity of glass microsphere/epoxy-matrix syntactic foam, some experiments and measurements were performed. The surface roughness of the glass-microsphere was reduced by a surface treatment. After making specimen having volume fraction 55 ~ 80% with treated and untreated glass-microspheres, the thermal conductivities of the specimens were measured. As the result, it was confirmed that the thermal conductivity of the syntactic foam with the surface-treated particles slightly decreased compared to the syntactic foam using the untreated particles.-
