The first 2MW ultra-low speed carbon fiber blades come out

The 2MW ultra-low speed carbon fiber blades jointly developed by CSR Times New Material and the National Defense Science and Technology University have been successfully tested. CSR Times New Materials has become the first company in the country to successfully develop such products.

In the field of wind power, as the blades of wind power continue to prolong and the power of generators continues to increase, the performance of traditional glass fiber composites has become insufficient. In order to ensure that the blade tips do not touch the tower under extreme wind loads, the blades must have sufficient strength. The most effective way to balance the weight and strength of the blades is to use carbon fiber reinforcement. Carbon fiber is a new high-strength, high-modulus fiber material with carbon content above 95%. It is softer than hair and harder than steel. Carbon fiber has become an important choice for the next generation of wind power blade materials.

This time, the development of the 2MW and 56.5m carbon fiber wind turbine blades jointly completed by the two parties stems from the "12th Five-Year Plan" technology major project of Hunan Province that was jointly undertaken by the two sides three years ago and the "Design and Preparation of Carbon Fiber Composite Materials Ultra-long Wind Blades" project. . The blade has applied a number of new technologies such as carbon glass hybrid and carbon fiber liquid molding. The blade weight has been reduced by 15%, the blade load has been significantly reduced, and the power generation efficiency has been further improved. This has effectively solved the ultra-low wind speed, long blade stiffness, and partial load. Big problem.

The relevant person in charge of CSR Times New Materials said that the successful development of 2MW ultra-low speed carbon fiber blades has effectively solved the problem of balance between lightness and strength and laid a technological foundation for the company's development of anti-typhoon blades and follow-up offshore super-large wind power blades. CSR Times New Material entered the wind power industry in 2007 and has now formed a complete wind turbine blade technology independent research and development system. The company has undertaken seven major national and provincial-level projects in the field of wind power blades, organized five revisions of corporate standards, and applied for 25 patents.
