초록

유기 복합 건축재에 적용하기 위하여 불포화 폴리에스테르/석분 복합재료에 기계적 물성과 접착성이 우수한 poly(vinyl alcohol) (PVA) 섬유를 도입하여 복합재료를 제조하여 기계적 물성을 평가하였다. 표면처리용 실란 카플링제로서 γ-methacryloxy propyl trimethoxy silane(γ-MPS)을 강화재 표면에 처리하여 실란 카플링제의 농도 변화에 따른 폴리비닐 알콜 섬유 강화 복합재료의 기계적 물성을 추적하였다. 강화재의 표면처리에 의한 복합재료의 기계적 물성은 현저히 증가하였으며, 적정 실란 처리농도에서 최대값이 나타났다. M700A/석분 복합재의 경우, 실란 처리 농도 0.8wt%에서 굴곡탄성율의 최대값이 나타났으며, 석분 함량 40wt% 일 때 굴곡탄성율 1.26 GPa로서 미처리시에 비해 28.5% 증가하였으며, M700A/PVA의 경우 폴리비닐 알콜 섬유 첨가량에 관계없이 실란 처리농도 0.6wt% 에서 굴곡탄성율의 최대값이 나타났다.

Rock-crush filled unsaturated polyester composites was reinforced with polyvinyl alcohol(PVA) short fiber, and their mechanical properties were evaluated. γ-Methacryloxypropyl trimethoxy silane(γ-MPS) was used for surface modification of reinforcement fiber and fillers. In the case of surface treated reinforcement, the mechanical properties of these composites were drastically increased compared to the untreated composites and showed maximum value at the optimum concentration of γ-MPS. Maximum flexural modulus of M700A/PVA composite showed at the γ-MPS concentration of 0.6wt%, M7004/rock-crush composite showed maximum flexural modulus value(1.26 GPa) at 0.8 wt% solution concentration of γ-MPS.
