Glass Reinforced Polymers (GRP) are typically used for which application?

• A. Boat hulls and canoes.
• B. Wooden furniture.
• C. Metal casings.
• D. Ceramic tiles.

Answer: (A)

Glass Reinforced Polymers mix glass fibers with a plastic resin to create a material that is strong, lightweight, and resistant to water and corrosion. Because of this combination, GRP is a great fit for marine structures where keeping weight down and resisting constant exposure to water are crucial. The ability to mold GRP into smooth, complex shapes makes it a common choice for boat hulls and canoes.

Other options don’t fit the typical needs as well. Wooden furniture relies on timber for aesthetics and feel, not the water-resistant, high-strength-for-weight benefits GRP provides. Metal casings are chosen for metal’s rigidity and heat properties, while ceramic tiles are brittle and suited to hard, flat surfaces rather than lightweight, impact-resistant hull material.
