## Question

Give the technical applications of fiber reinforced plastics.

## Short answer

FRP composites: aircraft and automotive panels, boat hulls, construction rebar, printed circuit boards, wind turbine blades, and sports equipment like bicycle frames.

## Answer

- **Aerospace and defence:** aircraft wings, fuselage panels, helicopter blades, rocket casings, body armour and helmets (aramid).
- **Automobile:** body panels, bumpers, leaf springs, racing car chassis.
- **Construction and civil:** reinforcing bars, strengthening of bridges and columns, roofing sheets, water tanks, pipes, chemical plant ducts.
- **Marine:** boat hulls and decks.
- **Electrical and electronics:** printed circuit boards (glass-epoxy), insulators, antenna covers.
- **Sports and energy:** tennis rackets, bicycle frames, golf shafts, wind turbine blades.
