This research paper presents the synthesis and mechanical characterization of Glass-Fiber Reinforced Plastic (Glass-FRP) and Natural Fiber-Hybrid Composites (NFHC) using hand lay-up techniques. The study aims to assess the mechanical characteristics of composites made from various natural fibers, including jute, flax, coir, and hair fibers, and to evaluate the impact of natural fiber addition on the composite's mechanical properties. The research emphasizes the importance of altering fiber type, orientation, resin type, and curing conditions to optimize composite characteristics for specific applications. The mechanical characteristics of the composites were evaluated through tensile and flexural testing. The results show that the incorporation of jute fibers significantly enhances the tensile strength and flexural strength of Glass-FRP composites, with the highest tensile strength of 71.29 MPa and flexural strength of 67.73 MPa. The study highlights that the combination of natural and glass fibers can produce lightweight, highly-strengthened composite materials with improved mechanical properties, suitable for a wide range of engineering applications. The research contributes to the ongoing efforts in sustainable and high-performance composite materials, providing valuable insights into the potential advantages and limitations of using natural fibers in Glass-FRP composites. The findings offer exciting possibilities for the development of composite materials that can meet the requirements of various engineering sectors.This research paper presents the synthesis and mechanical characterization of Glass-Fiber Reinforced Plastic (Glass-FRP) and Natural Fiber-Hybrid Composites (NFHC) using hand lay-up techniques.
