Mingyang has a professional blade technology R&D team consisting of nearly 100 members and leads the way especially in the blade segmentation technology and carbon fiber/fiberglass technology in the industry.
Blade Segmentation
The segmented blade technology independently developed by Mingyang solves the blade transportation problem caused by complex terrain, making contribution to turning some areas where wind power construction is impossible due to terrain restrictions into green energy production bases. The verification of 58.8m blade sample is completed and DNVGL certification is obtained, meeting the conditions of mass production, marking that Mingyang is the only complete machine manufacturer in China with segmented blade technology.
Carbon Fiber/Fiberglass Blending
The blade girder is made of carbon fiber/fiberglass mixture for weight optimization so that the material performance, especially the modulus, can be improved significantly while the material cost is increased to a certain extent. By changing the ratio of carbon fiber yarn to fiberglass, the modulus can be changed linearly from 46Gpa to 120Gpa, hence creating the possibility of design, optimization, weight reduction and cost reduction, and overcoming the limitation that the modulus of pure fiberglass cannot meet the design requirements of large blades at present. Additionally, the bottleneck of high cost of carbon fiber can be eliminated and the effect of 1+1 > 2 can be achieved. Mingyang also develops blade root embedded screw sleeve technology and independently designs the lightning protection system according to the characteristics of carbon fiber/fiberglass mixture.
