Zusammenfassung:The present invention relates to a method for manufacturing 5Mg(OH)2·MgSO4·3H2O (513MHSH) at low temperatures and atmospheric pressure and, more specifically, to a method for manufacturing 513MHSH capable of effectively and economically obtaining a 513MHSH fiber with high quality, high purity, and a high yield under a moderate condition for synthesizing a solution at low temperatures and atmospheric pressure by optimizing reaction conditions such as mixing of specific solvents, a mole ratio of starting materials, a reaction temperature, a reaction time, etc., and dramatically mitigating the conventional harsh hydrothermal synthesis condition at high temperatures and pressure to the 513MHSH manufactured by the method, and to a fiber-reinforced polymer composite material containing the same as a reinforcing agent. 본 발명은 5Mg(OH)·MgSO·3HO(513MHSH)의 저온상압 제조방법에 관한 것으로, 더욱 상세하게는 특정 용매의 배합, 출발물질의 몰비, 반응온도 및 반응시간 등 제반 반응조건을 최적화함으로써, 기존 고온고압의 가혹한 수열 합성조건을 획기적으로 완화시켜 저온상압의 온화한 용액 합성조건에서 효율적, 경제적으로 신속하게 고품질, 고순도, 고수율의 513MHSH 섬유를 수득할 수 있는 513MHSH의 제조방법, 이에 따라 제조된 513MHSH, 및 이를 강화제로서 포함하는 섬유강화 고분자복합재료에 관한 것이다.
