Polyurethanes build a better bond

Polyurethanes build a better bond

The trend toward longer turbine blades means greater energy capture at lower wind speeds. However, with bigger blades comes increased weight and stress on the adhesive bond line. Polyurethane adhesives can improve the long-term performance of future blades while reducing total manufacturing cost. To boost energy yield, rotor blades are becoming larger and heavier. The longest production blades can span about 61-m and weigh 15 metric tons. Future designs call for lengths of 80 to 100 m and beyond. They are primarily polymer composite structures (e.g. glass-reinforced plastic) expected to last at least 20 years in a challenging service environment. When rotor blade tips slice through the air at speeds up to 300 km per hour, it’s not hard to imagine the extreme stresses they must withstand.

		CASTROL OPTIGEAR SYNTHETIC X 320 To protect your wind turbine investment, especially when out-of-warranty, you need one of the world’s most advanced lubricants. Castrol Optigear synthetic x 320, is designed to deliver more sustained protection. Here is the evidence to prove it. More>>

		Study: Over 70 GW of RE online by 2020 The state of the US electric grid is a pivotal issue for the energy industry. The country’s transmission infrastructure has been subject to increasingly rigorous reliability standards and significant changes to power markets while also weakened by decades of under-investment.

		New study explains trends in wind turbine prices over past decade Since 2008, wind turbine prices in the U.S. have fallen by nearly one-third on average. In conjunction with improvements in turbine design and performance, falling turbine prices enable the latest generation of wind power projects to profitably sell electricity at prices well below what was common several years ago.

		New ideas in medium-voltage circuit breakers Renewable energy sources will help meet the challenge of electrical energy consumption which is projected to double in the next 20 years. Wind power, a critical part of the solution, is one of the fastest growing sectors of the global power generation industry. More>>

		MIT profs look offshore for better wind Of all the zero-carbon energy sources available, wind power is the only one that’s cost-competitive today: A 2006 report by the U.S. Energy Information Administration put the total cost for wind-produced electricity at an average of $55.80 per megawatt-hour, compared to $53.10 for coal, $52.50 for natural gas and $59.30 for nuclear power.
