Composite materials can reduce the environmental impact of a structure or vehicle through their durability, resistance to rot and corrosion, low weight and insulating properties. For example:
- Fiberglass window lineals and doors do not rot, rust or swell, resulting in fewer air leaks and better seals than wood and steel products. The components provide inherent insulation value that far exceeds aluminum and steel products.
- The heavy truck industry has moved to predominately composite bodies. This reduces weight and allows for more freight to be carried, so fewer trips are required, and also provides for significant fuel savings when the vehicle is empty.
- Wind turbines blades made of composites can be significantly longer than wood blades, better facilitating energy production.
- Scrubbers and stacks made of composites are better at resisting corrosive flue gas desulfurization and other scrubbing operations. This allows industrial and utility operations to remove air contaminants under conditions that would cause traditional metals to fail very quickly.
