Which statement best describes carbon fibre reinforced polymers (CFRP)?

• A. Composite with great strength to weight ratio; carbon fibres woven together and encased in polymer resin.
• B. A natural fibre reinforced polymer.
• C. A ceramic composite.
• D. A metal alloy used in construction.

Answer: (A)

Carbon fibre reinforced polymers are composites where carbon fibres carry the main load while a polymer resin binds the fibres and holds them in place. The fibres provide very high strength and stiffness, and the resin protects the fibres and helps transfer loads between them. When the fibres are woven and laid in layers, engineers can direct strength in specific directions, giving an outstanding strength-to-weight ratio compared with many metals or polymers alone. This lightweight, strong combination makes CFRP ideal for aerospace, motorsport, and high-performance equipment. It isn’t a natural fibre reinforced polymer, since the fibres are synthetic. It isn’t a ceramic composite, because the matrix is a polymer, not ceramic. It isn’t a metal alloy, as there’s no metal involved.
