Abstract :
Polymeric nanocomposites are increasingly recognized as a suitable alternative to traditional metallic and polymeric materials and often offer better overall performance in many cases. These materials are particularly used in various industries such as transportation, automotive, aerospace, and shipbuilding due to their light weight, high strength, and low cost. The results show that the addition of carbon nanofibers to the epoxy resin matrix significantly improves mechanical properties, including tensile strength, modulus, and fracture toughness. Furthermore, carbon nanofibers enhance the thermal stability of resins and reduce their degradation rate at high temperatures. The use of modern methods such as surface modification of nanofibers and advanced mixing techniques leads to significant improvements in the dispersion of nanofibers in the epoxy resin matrix and enhances the mechanical and thermal properties of the composites. Research results indicate that carbon nanofibers, especially compared to other reinforcing materials, perform better in preserving the thermal and mechanical properties of epoxy composites. This study analyzes the impact of carbon nanofibers on the morphology, mechanical properties, thermal stability, and thermal degradation behavior of epoxy resin and hybrid epoxy nanocomposites. The research additionally reviews recent advancements and significant results in the innovative development of epoxy nanocomposites containing carbon nanofibers, highlighting their potential applications and benefits.
