Geopolymer materials have excellent properties such as high strength, low thermal conductivity, fire resistance, acid and alkali resistance, and low carbon emissions. They can be used as protective engineering materials in places with explosion risks. At present, the common composite blast resistant panel is in the form of a sandwich: the outer layer isgalvanized steel plate, and fiber cement board or calcium carbonate board is used as the inner layer material, as these boards have the advantages of easy installation, good fire resistance, and explosion resistance. This study investigates the effect of adding different types of fibers to geopolymer mortar on the mortar's basic mechanical properties, such as compression strength, bending strength, and impact resistance. The explosive resistance of the fiber-reinforced geopolymer mortar blast resistant panels was evaluated through free-air explosion. In this paper, experimental procedures and numerical simulation have been performed to study the failure modes, maximum deflection, and dynamic response of the fiber-reinforced geopolymer mortar blast resistant panel under free-air explosion. The research results can provide a reference for the design and production of blast resistant panels.
地聚合物材料具有高强度、低导热性、耐火性、耐酸碱和低碳排放等优异性能。它们可作为有爆炸风险场所的防护工程材料。目前，常见的复合防爆板为夹心形式：外层是镀锌钢板，内层材料采用纤维水泥板或碳酸钙板，因为这些板材具有安装方便、耐火性和防爆性好的优点。本研究调查了向地聚合物砂浆中添加不同类型纤维对砂浆基本力学性能（如抗压强度、抗弯强度和抗冲击性）的影响。通过自由空气爆炸评估了纤维增强地聚合物砂浆防爆板的抗爆性能。本文进行了实验程序和数值模拟，以研究纤维增强地聚合物砂浆防爆板在自由空气爆炸下的破坏模式、最大挠度和动态响应。研究结果可为防爆板的设计和生产提供参考。
