Abstract

In this study, we performed experimental tests on five SP-100 aluminum powder epoxy specimens with several after-curing conditions in order to estimate their hardness with temperature and compressive strength. In the surface hardness test, it was found that the higher the after-curing temperature, the higher was the hardness. In particular, it was found that the hardness of the specimens in cases 3 and 4 was much higher than in the other cases. In addition, in the compression tests carried out to evaluate the compressive strength, it was found that the specimens showed relatively similar stiffness and strength with after-curing, and specimens with no after-curing showed compression stress-strain curves similar to those of thermoplastic resins.

본 연구에서는 SP-100 알루미늄 분말 에폭시의 경도 및 압축강도를 평가하기 위해, 후경화 조건을 달리한 5 종류의 시편에 대해 온도별 경도 측정 시험과 압축강도시험을 수행하였다. 온도별 표면경도 시험 결과, 후경화 온도가 높을수록 경도가 높게 나타나는 것을 확인하였다. 특히, Case 3과 Case 4의 경우가 다른 Case의 시편에 비해 상대적으로 높은 경도를 보임을 알 수 있었다. 압축시험을 통한 시편의 압축강도는 후경화를 실시한 시편들이 비교적 유사한 강성 및 강도를 나타내었으며 미실시한 시편은 열가소성 수지와 같은 압축응력곡선을 나타내었다.
