초록
Sheet Molding Compound(SMC) 욕조 생산시 발생하는 폐 FRP 스크랩을 재활용하기 위하여 불포화 폴리에스테르 수지를 결합재로 하고, 산소플라즈마를 이용하여 표면처리한 폐 FRP를 충진제로 하여 복합재를 제조하였다. 제조한 복합재내의 충진제 함량이 변화에 따른 복합재의 기계적물성에 미치는 Plasma 표면처리 영향과 결합재와 충진제간의 계면현상을 관찰하였다. 굴곡탄성률과 충격강도는 충진제의 함량이 70 wt%일 때 2.74 GPa와 1.5 KJ/m(2)로 최대값을 나타내었다. 또한 결합재와 충진제간의 계면결합현상을 확인하기 위하여 충격강도 측정후의 시편을 SEM 관찰 결과 산소플라즈마를 이용하여 표면 처리한 충진제 보강 복합재의 계면에서는 상분리 현상이 없음을 확인할 수 있었다.
In order to recycle FRP waste, which is generated when SMC(Sheet Molding Compound) bathtubs are produced, we made a composite by using unsaturated polyester resin, as the matrix, and FRP waste, the surface of which was treated by oxygen Plasma, as the filler. We observed the interfacial phenomenon between the matrix and the filler by studying the effect of Plasma surface treatment, which changed the content of filler in the composite produced, on the mechanical property of the composite. When the content of filler was 70 wt%, the flexural modulus and impact strength were at the maximum, 2.74 GPa and 1.5 KJ/m(2), respectively. In addition, SEM of the sample after measuring impact strength showed that there was no phase separation in the surface of filler reinforced composite that had been treated with oxygen plasma.
