The article "Fiber-Reinforced Polymer Composites: Manufacturing, Properties, and Applications" by Dipen Kumar Rajak et al. provides a comprehensive overview of fiber-reinforced polymer composites (FRPCs). FRPCs are gaining importance due to their high strength-to-weight ratio, durability, stiffness, damping properties, and resistance to corrosion, wear, impact, and fire. These materials are widely used in various industries, including mechanical, construction, aerospace, automobile, biomedical, and marine. The authors discuss the classification of composites based on their constituents, such as natural and synthetic fibers, and the manufacturing techniques used to produce them. They highlight the advantages of using natural fibers, which are abundant, biodegradable, and cost-effective, over synthetic fibers. The article also covers the challenges and environmental concerns associated with composite waste and the development of eco-friendly recycling processes. Key manufacturing techniques for FRPCs are detailed, including conventional methods like hand lay-up, spray-up, vacuum bag molding, resin transfer molding (RTM), and advanced techniques such as electrospinning, additive manufacturing (AM), and automated processes like filament winding and robotic tape layup. Each technique is evaluated for its advantages and applications. The applications of FRPCs in civil and mechanical engineering are extensively discussed. In civil engineering, FRPCs are used in fire-resistant concrete, bridge systems, earthquake-resistant columns, and pile materials. In mechanical engineering, they are applied in gear pairs, pressure vessels, hydraulic cylinders, and headstock materials. The article emphasizes the significant improvements in performance and cost-effectiveness that FRPCs offer compared to traditional materials. Overall, the article underscores the potential of FRPCs in addressing the growing demands for lightweight, high-performance materials in various industries, while also highlighting the need for optimized manufacturing techniques to enhance their characteristics for specific applications.The article "Fiber-Reinforced Polymer Composites: Manufacturing, Properties, and Applications" by Dipen Kumar Rajak et al. provides a comprehensive overview of fiber-reinforced polymer composites (FRPCs).
