STUDY OF ADHESION AT THE POLYMER-SILICATE COMPOSITE INTERFACE UNDER THE INFULENCE OF PHYSICO-MECHANICAL FACTORS

This paper investigates the potential of additive manufacturing for the production of polymer-based reinforcing elements designed to improve the structural properties and durability of silicate composites. The research addresses the interaction between polymer reinforcements and silicate composites, with a particular focus on the synergy at the material interface under physico-mechanical and environmental stresses. The aim is to increase both mechanical strength and resistance to degradation caused by water and chemical de-icing agents. Concrete composites reinforced with different 3D printed polymeric elements were experimentally tested for flexural and compressive strength as well as long-term durability. The results showed that optimized reinforcement geometry and material selection can lead to a significant improvement in composite properties. The high-performance concrete combined with appropriately designed polymer elements showed the greatest increase in compressive strength, while the conventional concrete benefited mainly in terms of flexural properties. In addition, some polymer reinforcements contributed to the maintenance of adhesive bonds even after prolonged exposure to aggressive environments. These findings confirm the viability of using additive manufacturing to create functional reinforcements tailored for cement-based materials, offering a new and adaptable approach to designing composites.本研究探讨了增材制造（additive manufacturing）用于制备聚合物基增强体（polymer-based reinforcing elements）的潜力，该类增强体旨在提升硅酸盐复合材料（silicate composites）的结构性能与耐久性能。研究聚焦聚合物增强体与硅酸盐复合材料之间的界面相互作用，重点关注材料界面在物理力学荷载与环境荷载作用下的协同效应。本研究的目标在于同时提升复合材料的机械强度，以及其抵御水与化学除冰剂侵蚀的能力。研究团队对搭载不同3D打印聚合物增强体的混凝土复合材料开展了抗弯强度、抗压强度与长期耐久性的实验测试。结果显示，优化后的增强体几何构型与材料选型可显著改善复合材料的综合性能。其中，搭配经过合理设计的聚合物增强体的高性能混凝土，其抗压强度提升最为显著；而普通混凝土则主要在抗弯性能上获得增益。此外，部分聚合物增强体即便在长期暴露于侵蚀性环境后，仍可维持粘结界面的结构完整性。上述研究结果证实了利用增材制造制备适配水泥基材料（cement-based materials）的功能性增强体的可行性，为复合材料设计提供了一种全新且灵活可调的技术路径。
