Comprehensive Review of Manufacturing Techniques for Fiber Reinforced Polymer (FRP) Composites: Bridging Conventional Methods and Advanced Technologies

FRP composites, prized for their strength-to-weight ratio and corrosion resistance, are pivotal in engineering. This review analyzes traditional (e.g., hand lay-up, filament winding) and advanced (e.g., automated tape laying, resin transfer molding) manufacturing techniques, comparing short- and long-fiber reinforcement methods. It addresses gaps in prior literature by systematically evaluating their advantages, limitations, and industrial applications, emphasizing material properties, cost, and scalability. Emerging innovations like automated fiber placement and sustainable molding techniques are highlighted for enhancing performance and eco-efficiency. Tailored for aerospace, automotive, and civil engineering sectors, the review provides actionable insights for optimizing FRP use. By consolidating fragmented knowledge, it serves as a critical resource for researchers and professionals navigating FRP manufacturing trends and future advancements. This paper offers a novel, integrated analysis of traditional and advanced FRP manufacturing techniques, systematically comparing short- and long-fiber reinforcement methods while addressing gaps in prior literature. It uniquely evaluates processes like automated fiber placement and resin transfer molding, emphasizing sustainability and scalability, and provides actionable insights for optimizing FRP applications across aerospace, automotive, and civil engineering sectors.
