High-Performance Hull System
A high strength, recyclable composite material with hybrid characteristics of both glass fibre and carbon fibre
By 2050, global annual wind turbine blade waste will reach 2.9 million tons, with 43 million tons of cumulative wind turbine blade waste. China, Europe, United States and the rest of the world will have 40%, 25%, 16% and 19% waste respectively.
Wind turbine blades can last up to twenty years, but many are taken down after just ten years, so they can be replaced with bigger and more powerful designs. Tens of thousands of aging blades are coming down from steel towers around the world and most have nowhere to go but landfill.
ExoWindTM presents a ‘fit for purpose’ and viable solution in response to this global ecological crisis by providing an accelerated green transition to a circular economy for the wind energy industry.
As ExoWind™ exhibits shared hybrid characteristics of both glass fibre and carbon fibre. That said, ExoWind™ is considerably stronger than glass fibre. Carbon fibre is used to cope with centrifugal forces. The tip of a large wind turbine blade can exceed speeds over 400km/h (250mph). Carbon fibre has a greater longitudinal tensile strength over glass fibre but suffers with a break-point at impact (i.e. hail, wind gusts etc). ExoWind™ has superior longitudinal tensile strength over carbon fibre (CF: 900MPa / DANUTM: 1020MPa).
ExoWind™ can replace both glass fibre and carbon fibre elements. It will provide increased safety strength on mechanical requirements and will resolve the current end-of-life issues.
