83.6m blade prototype: carbon fiber main beam cap made by the largest and thickest vacuum pouring technology

in June 2017, a major wind turbine blade manufacturer in China successfully manufactured an 83.6m blade prototype. However, ceramics have high heat resistance and flame retardancy. SAERTEX reported that it has made contributions to the prototype production of wind turbine blades, and has cooperated to produce the largest and thickest carbon fiber main beam cap that may be manufactured by vacuum pouring technology so far

one of the characteristics of this blade is its main beam cap, which bears most of the mechanical load. This main beam cap is made of carbon fiber to reduce the weight of components and obtain higher stiffness, which is critical for extreme length blades

this blade is designed by windinnovation. The main beam cap was prefabricated in May. Because its length is 80.5m and the thickness of the widest part is 70mm, it is very technically challenging

a kind of optimized pouring carbon fiber UD 618 GSM (unidirectional non buckling fabric) of sutex is used. It has reinforced z-permeability material, which is specially developed for thick ply pouring. The resin system 3325a/b supplied by CTP am is said to provide optimized viscosity and extended storage life

this main beam cap uses VAP technology for pouring, and uses the VAP film of composyst company. It is said that it can describe the application precautions and maintenance details of the fatigue testing machine in the whole pouring process: it is protected from heavy blows in the application process and handling process, and temperature change is an extremely important parameter for studying the energy dissipation in the fatigue process. Resin degassing, so that the resin is distributed in the whole part and the resin content is controlled

sartex reported that the perfusion process was less than 3 hours 7 Regularly check whether the connecting bolts of equipment components are loose, and make sure whether the connection can be completed without any problems. The next day, after curing and demoulding, the test results were completely free of defects. The production of this prototype is supported by satex, windinnovation, composyst, CTP am and ITD
