Abstract- – This study explores the mechanical and morphological behavior of PVC-coated nylon hybrid composites with a focus on their suitability for structural applications. Hybrid composites combining natural and synthetic fibers offer a sustainable alternative with enhanced mechanical and thermal properties. In this research, waste nylon fibers were reinforced into a PVC matrix, alongside calcium carbonate fillers and surface modifiers, to improve strength, stiffness, and water resistance. Various fabrication techniques, including vacuum infusion and compression molding, were employed to ensure uniform fiber dispersion and strong interfacial bonding. Mechanical properties such as tensile, flexural, and impact strength were evaluated, along with thermal stability via TGA and DSC, and viscoelastic properties using DMA. SEM and TEM analyses were used to assess the microstructure and dispersion of fillers. The results indicate that the optimized hybrid composite demonstrates improved mechanical performance, reduced water absorption, and enhanced durability. These characteristics make the material a viable choice for automotive, construction, and aerospace structural applications.
