The development of E7 high-performance fiberglass fabric, which can be produced on a large scale, make it possible to meet the large demand of wind energy, high pressure vessels, pultrusion and other industries for high mechanical requirement, its major target market is that the rapidly growing wind power heavily depends on the length of wind blades, and larger blades can capture more wind energies while also requiring higher strength and modulus for fiberglass reinforced material. By adapting E7 fiberglass fabrics, the manufacturer can make lighter products with better performance, higher efficiency and longer life time, which will lead to the lower power generation cost in the end.
