Slag fiber has economic and environmental advantages in that it converts a low-value-added material to a high-value-added material. However, although the slag fiber has a chemical composition similar to basalt fiber, its competitiveness in the fiber industry is significantly lower. Moreover, the slag fiber remains in the pre-commercial stage due to the uncertainty and instability of the basic properties. Therefore, in this study, the slag fiber customized through the fiberization process was compared with the existing basalt fiber to analyze the effect of the similarity of chemical composition on the environmental degradation characteristics and mechanical properties under tensile loading. As a result, the slag filament composites showed lower tensile strength due to the weaker interfacial bonding strength with the epoxy matrix than the basalt filament composites, but the difference in decreased tensile strength rate was not significant. In addition, long-term moisture absorption in fresh water and seawater demonstrated excellent moisture absorption resistance.

环氧浸渍连续玄武岩与矿渣长丝复合材料吸水性能对拉伸性能的比较

矿渣纤维具有将低附加值材料转化为高附加值材料的经济和环境优势。然而，矿渣纤维虽然具有与玄武岩纤维相似的化学成分，但其​​在纤维行业的竞争力明显较低。此外，由于基本性能的不确定性和不稳定性，矿渣纤维仍处于预商业阶段。因此，本研究通过纤维化工艺定制的矿渣纤维与现有玄武岩纤维进行比较，分析化学成分相似性对拉伸载荷下环境降解特性和力学性能的影响。因此，与玄武岩长丝复合材料相比，矿渣长丝复合材料与环氧树脂基体的界面结合强度较弱，因此其抗拉强度较低，但抗拉强度下降率差异不显着。此外，在淡水和海水中长期吸湿表现出优异的抗吸湿性。
