Introduction

Fibre Reinforced Polymer (FRP) composites are advanced materials composed of a polymer matrix reinforced with high-strength fibres like carbon, glass, or aramid. These materials combine lightweight properties with exceptional strength and corrosion resistance, making them ideal for high-performance applications.', 'Manufacturing': 'FRP composites are manufactured through processes such as hand lay-up, resin transfer moulding (RTM), pultrusion, and filament winding. Fibres are embedded in a resin matrix, cured under heat and pressure, and shaped into desired forms for industrial use.', 'Applications': 'In aviation, FRPs are used in aircraft structures (e.g., fuselage, wings) to reduce weight and improve fuel efficiency. In automobiles, they enhance fuel economy and safety by replacing metal components in body panels, chassis, and interior parts, while also enabling design flexibility.

Conclusion

FRP composites are pivotal in modern engineering, driving innovation in aerospace and automotive sectors through their superior mechanical properties and sustainability benefits.
