Currently, research has confirmed the significant potential of 3D printed polymer lattices in enhancing the mechanical properties of cement-based composites. Polymer materials are influenced by high-temperature environments. This study aims to further explore the impact of 3D printed lattice structures on the compressive mechanical properties of cement-based materials under high-temperature conditions. The approach employed in this paper involves utilizing the multiple jet fusion (MJF) technique to fabricate two types of lattices with the same volume fraction within cement-based samples. Uniaxial compression experiments were carried out on cement-based samples both with and without the 3D printed lattice at room temperature, 50 °C, and 100 °C. The research explores the compressive properties of cement-based samples reinforced with different lattice structures at varying ambient temperatures. Additionally, digital image correlation (DIC) technology was utilized to analyze the deformation characteristics of the samples. The experimental results demonstrate that the 3D printed lattice effectively enhances the compressive properties of cement-based materials. However, it is worth noting that the cement-based samples reinforced with this material exhibit higher temperature sensitivity compared to the lattice-free reinforced samples.
目前，研究已证实3D打印聚合物晶格在增强水泥基复合材料力学性能方面具有巨大潜力。聚合物材料会受到高温环境的影响。本研究旨在进一步探究3D打印晶格结构在高温条件下对水泥基材料抗压力学性能的影响。本文采用的方法是利用多射流熔融（MJF）技术在水泥基样品中制备两种体积分数相同的晶格。在室温、50℃和100℃下，对有和没有3D打印晶格的水泥基样品进行单轴压缩试验。该研究探讨了在不同环境温度下，用不同晶格结构增强的水泥基样品的压缩性能。此外，利用数字图像相关（DIC）技术分析样品的变形特性。实验结果表明，3D打印晶格有效地增强了水泥基材料的压缩性能。然而，值得注意的是，与无晶格增强样品相比，用这种材料增强的水泥基样品表现出更高的温度敏感性。
