Advantages:
1. High strength-to-weight ratio: Fiber-reinforced polymers have a significantly higher strength-to-weight ratio compared to traditional construction materials like steel and concrete.
2. Corrosion resistance: Since FRP composites do not corrode, they are ideal for use in corrosive environments. They are also resistant to chemicals and provide better durability.
3. Easy to install: FRP components are easy to transport, cut and install, making them a popular choice for retrofit applications.
4. Durability: FRP composites have demonstrated long service life, even in harsh environments such as coastal areas.
5. Design flexibility: Due to their high strength-to-weight ratio and the ability to generate compound shapes, these composites offer greater design flexibility.
Disadvantages:
1. Cost: Fiber-reinforced polymers could be more expensive than traditional construction materials, particularly for large projects.
2. Fire resistance: Fire safety standards and regulations have not yet been fully developed. Additionally, the combustion of FRP composites generates poisonous gases thereby further limiting their structural application.
3. Durability under repeated loadings: Repeated loading may cause fatigue damage in the composite structure.
4. Relatively new technology: The technology of fiber-reinforced polymers is relatively new and therefore still not extensively tested.
5. Cultural concern: There may be a relative lack of trust in modern composite materials, which may lead to objections to their use in buildings and structures.
