Pultrusion manufacturing techniques were developed for producing lengths of reinforced polymer with constant cross-sections. This provides the raw materials used for cost-efficient alternatives to conventional construction materials such as steel and wood. Originally manufactured because of their lightweight characteristics, FRP products can now contend with the strength of structural steels on a pound-for-pound basis, displaying a reduced weight profile of up to 80%.
They are also impervious to rot and display excellent chemical inertness to an excess of corrosive elements, opposing the natural degradation linked to wooden elements. These mechanical characteristics signify a distinct cutback in energy-intensive maintenance and possible replacement requirements that can have further implications for material recovery and recycling.
Most vital in the context of sustainability, FRP manufacturing represents a radically reduced environmental impact over the traditional material preparation methods. Pultrusion of virgin FRP materials produces less greenhouse gases and use a lesser amount of energy than the manufacturing of steel, aluminum, and concrete.
It has also been confirmed to show a reduced environmental impact over aluminum and steel recycling method in terms of air and water output, and energy consumption.
Regardless of the existing environmental benefits of FRP manufacturing and application, ongoing efforts are ongoing to make sure that modern production methods are in-line with changing global compliances and ethical standards.
