Q10.What is an FRP composite material? How are they manufactured? Discuss their applications in the aviation and automobile industry

FRP (Fiber-Reinforced Polymer) composites are advanced materials comprising high-strength fibers like glass, carbon, or aramid embedded within a polymer matrix (resin). They are valued for their exceptional strength-to-weight ratio and superior corrosion resistance.

Manufacturing Process

Manufacturing involves impregnating fibers with a polymer resin, followed by curing. Common techniques include hand lay-up, spray lay-up, filament winding, pultrusion, and resin transfer molding (RTM), each suited for different part geometries and production volumes.

Applications in Aviation Industry

• Fuselage, wings, and tail sections, significantly reducing aircraft weight.
• Interior panels and engine components, enhancing fuel efficiency and structural integrity.

Applications in Automobile Industry

• Lightweight body panels, chassis components, and interior parts.
• Drive shafts, improving fuel economy, safety, and design flexibility.
