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.
