Epoxy resins are widely used in various industries due to their excellent properties, such as chemical resistance and good adhesion. However, there is a pressing need to develop fire-resistant epoxy resins because they tend to burn easily and produce a high amount of smoke at elevated temperatures. Halloysite, a mineral characterized by its tubular structure and high thermal stability, is recognized as a promising option for enhancing the fire resistance of epoxy resins. Epoxy nanocomposites that incorporate halloysite nanoparticles, particularly after their surface modification, demonstrate improved mechanical and thermal properties. Achieving proper dispersion of nanoparticles within the epoxy matrix and minimizing their agglomeration are crucial for enhancing thermal stability and mechanical performance. Epoxy nanocomposites are considered some of the most advanced composite materials across a range of industries. By combining epoxy resins with nanoparticles, these materials exhibit unique properties that can significantly enhance the performance and durability of final products. This study provides a detailed examination of the morphology, mechanical, and thermal properties of epoxy nanocomposites while analyzing the impact of nanoparticles on the characteristics of these materials. The findings of this research may facilitate the development of new applications and optimize production processes in various industries. Additionally, this research can contribute to the creation of new materials with optimal properties for industrial and engineering applications.
