AB  - The two distinct types of composite materials (5% to 10%) were developed using recycled polyvinyl alcohol fiber (RPA), silicon nitride fiber (SN), and reduced carbon nanoparticles (RCN). Enhanced microstructural properties and mechanical strength were attained through the application of the 3-glycidoxypropyltrimethoxysilane coupling method. The combination of the resin-like properties of RPA-SN fiber resulted in the formation of robust outer strength and a high bonding structure. RPA-RCN composite materials with a weight percentage of 10% exhibited a tensile strength of 42 MPa. In contrast, RPA-SN-RCN composite materials containing 5% to 10% demonstrated enhanced tensile, bending, and hardness properties. Pyramid structures, solid structures, and crystal phases were formed using RCN particles. The resin and silane properties on hardness were gradually 14% increasing the outside region, whereas RPA-SN-RCN (10 wt%) on average hardness were attained at 86 (Shore-D). The microstructures on RPA-RCN (5% to 10%) samples were observed solid structure, twin boundary’s structure and lattice structure. The tensile strength of RPA-SN-RCN (10%) was 67.3 MPa, whereas the impact strength of RPA-RCN (10 wt%) was 53 J/mm<sup>2</sup>. The scanning electron microscopies (SEM) were used to investigate the microstructure of the RPA-SN-RCN (5%) and RPA-SN-RCN (10%) composite materials, respectively.
