The development of sustainability in industry has made it imperative to utilize waste and accessible natural resources properly. Our goal is to transform the naturally occurring resources, tamarind seed powder (TSP), eelgrass (EG), and adamant creeper (AC), into goods that are beneficial to society. In this study, different weight proportions of alkali-treated AC, EG, and TSP were combined to make hybrid natural fiber (NF) composite materials using the hand layup process. The material strength of the alkali treated (15% AC, 20% EG, and 15% TSP) composite sample was attained 211 MPa, 278 MPa, 21.7 J/m2, and 84.6 for tensile, flexural, impact, and hardness in that sequence. The storage modulus, loss modulus, and mechanical loss factor were measured and plotted against temperature in a dynamic mechanical analysis (DMA) experiment. All composites had higher storage and loss moduli and a lower mechanical loss factor, indicating more elastic properties. The findings demonstrated that adding fiber-filled TSP fillers tended to make the epoxy matrix more viscoelastic stiffness. As the weight percentage of fibers in the composite increases, discernible changes in the structural damping capacity have also been noticed. The thermal characteristics of composites were inspected by thermogravimetric analysis (TGA), and the TGA outcomes substantiated that the thermal constancy of a 20% EG-reinforced composite was good. The mechanical, dynamic, and thermal qualities of this composite material will yield significant benefits for the industrial sector.
