Cosco successfully installed the first polyurethane fan blades

CoscoTron, the world's leading supplier of high-performance polymer materials, recently announced that the first set of fan blades made from its polyurethane resins has been successfully installed and put into operation, marking another milestone in the commercialization of polyurethane resins as fan blade materials. This material better meets the needs of the wind power industry for a new generation of longer, stronger blades.
the fan blades (model WB113-PU) installed this time are 55.2 meters long and have a power of 2 megawatts, and their main beams and abdominal plates are made of Coscotro polyurethane resin . The fan was recently installed at a wind farm in Tieling City, Liaoning Province, operated by Liaoning Datang International New Energy Co., Ltd.
longer fan blades are a new trend in the wind power industry, and improving the blade's ability to resist wind pressure on higher towers has become a new challenge. Cosco has developed a polyurethane resin material for fan blade production to meet this new requirement. Cosco's research and development teams around the world work closely with a wide range of partners up and down the industry chain, including blade manufacturers, machine manufacturers, fiberglass manufacturers, equipment suppliers and blade design teams.Julien Guiu, Vice President, Marketing Asia Pacific,
Coxtron Polyurethane Business Unit, said: "The successful installation and operation of the fan pilot project in northeast China is an endorsement of the strength of Cosco's polyurethane resin material and demonstrates that the material is ready for use in the field of fan blades. We want to take this opportunity to send a strong signal to our industry partners that the time has come to use polyurethanes to make longer and stronger fan blades. In
to obtain certification, new fan blades must pass a variety of rigorous third-party tests. In order to ensure that fan blades can achieve long-term stable operation requirements in harsh environments, Cosco has conducted a comprehensive test of fan blade performance, and successfully passed the Beijing Certification Center (CGC) static and fatigue testing (including swing and swing direction).
fan blades are usually made of special fiberglass reinforced resin and are manufactured by vacuum perfusion technology. The successful application of polyurethane composites to the manufacture of large fan blades proves that polyurethane resins themselves have excellent mechanical properties and anti-fatigue properties. At the same time, due to the fast curing speed of polyurethane and good processing performance, blade manufacturers can shorten production time and improve production efficiency.
In addition to the fan blades installed and shipped in the Northeast, Cosco has developed a 59.5-meter-long, 2.2-megawatt blade with a 59.5-meter-long, 2.2-megawatt blade made of Coxtron polyurethane resin and installed in south-central China.
Added: "We have installed two sets of fan blades in wind farms across China to test the operational viability and stability of the blades under different wind conditions. This will provide valuable data for future blade design and help us further contribute to wind power as a renewable energy source. "
