Wind energy is in but field of second birth energy continues to hold dominant position, and be all the time go up big fibre glass strengthens composite material market. As blade longer and longer, blade manufacturer is being searched in the method that large construction weight does not reduce below the circumstance of sacrificial function, also using carbon fiber. Wind report lamina remains the crucial market territory of composite material. According to Acumen Research And CoNsulting " industry analysis, market dimensions, good luck and forecast, 2017–2023 year " forecast, the value of market of composite material of wind- driven turbine may exceed 12 billion dollar to 2023, and predict to 2023 will with of 9.6% compound year of increase rate growth. In recent years, as the frequent promotion of power of wind- driven dynamo, wind report lamina forward large change, light quantify, intelligence changes respect development, the function such as the intensity of material of this pair of lamina and stiffness raises new requirement. So, how to optimize composite material to manufacture technology, promote material property, ensure wind report lamina is stable and reliable? Zhu Jingchun of president of limited company of technology of electric combination motivation says the state: Application of innovation of “ composite material is a when promote development of wind cable industry fundamental strength, also be a when realize innovation of wind cable technology main engine. We want technology of innovation forward position, development quantifies carbon fiber composite material brand-new high strenth, gently, high quality of low cost of industry of safeguard wind cable develops. ”Composite material effect is main 　 in recent years, wind report lamina realizes rapid development, blade length comes from the 40-50 rice growth 2015 the 80-90 rice nowadays even 100 meters of above. In blade production technology upgrades ceaselessly in the process, composite material is the core material of wind report lamina, have crucial effect, deciding the cost of blade, function, value. “ wind report composite material is the data with required place of wind report lamina, having major effect to the function of blade, intensity especially. ” but advanced and advisory Du Anping says commission of major of wind energy of society of second birth the sources of energy, current, wind cable industry has entered par online period, group of electric machinery of high capacity wind will make dominant product, and the quality that composite material quality and function matter to group of wind electric machinery directly and cost. Zhu Jingchun says: No matter “ is onshore wind report or maritime wind report, group of wind electric machinery is moved toward gradually large change, this needs big lamina to prop up. After blade achieves certain length, composite material goes to very main effect since innovation application. On one hand, can make blade longer, lighter, function more actor; on the other hand, also can improve load of pneumatic of group of wind electric machinery, increase electricenergy production, reduce cost per kilowatt hour of the electricity generated by WECS. ”In September 2018, 3 water chestnut weigh labour dimension Si Dasi (MHI Vestas) the rated power that announces platform of its V164 turbine already achieved 10 million to cover with tiles, become a Taiwan businessman to count wind- driven turbine with two-step. Although the turbine of 10 million tile wants to just can be installed 2021, but the European sea of the Vattenfall in bay of Scotland A Bai Ding is windward in April 2018 electric deploy center (EOWDC) deploy the V164 with 8.8 made of baked clay million. Height is 191 meters, every lamina is 80 meters long. At the beginning of 2019, xi Menzi Gamesa but company of second birth energy (SGRE, spanish Zamudio) rolled out SG 10.0-193 DD, a 10 million made of baked clay above that this is this company is maritime and wind- driven dynamo. It has 94 meters long blade (the length of every lamina and a football ground are same) , offer 29, of 300 square metre sweep sweep past an area. Allegedly enough is year of electricenergy production of a SG 10.0-193 DD about 10, power supply of 000 Europe household. In addition, beautiful Sa of Xi Menzi song is being built in Danish Aoerbao on testing stand of big lamina of wind- driven turbine. This site aux will be able to is quite right lamina of next generation SGRE rotor have full-scale test, and hopeful is in operation was thrown in the round before the bottom 2019. According to the report, approve a test to will be on the 94 meters long lamina of SG 10.0-193 DD undertake. “ lamina design, make the stand or fall that reachs moving position affect wind report directly overall performance and generate electricity efficiency. Fiber of stone of ” Zhejiang constant base Xia Xiaolin of manager of department of research and development of limited company product represents industry, use new-style composite material, can promote wind report lamina mechanical function, fatigue property, shorten blade production is periodic, reduce blade to produce cost. “ for instance, blade uses polyurethane data, its are mechanical function promotion extent is in 15%-20% . In the meantime, blade girder cost can reduce 5%-10%” . Fall urgently a synergism 　 rapid development as blade industry, the domain obtains bigger breakthrough related blade material, but the bottleneck that still is put in the respect such as function, cost. Du Anping thinks, the many conditions such as blade length, weight, load, electricenergy production, cost restricted the development that quantifies fan lamina high-powered, high capacity, train in excess specified length, gently, and these restrict element in the final analysis is application of innovation of composite material of wind report lamina. On one hand dependency of composite material of lamina of homebred wind report can remain to rise, on the other hand the cost of composite material remains to reduce. Current, blade cost holds fan price totle drilling cost about 20% the left and right sides, blade material holds blade cost 80% , even 85% above. Xia Xiaolin says, current, high-powered data basically has market main trend two kinds big: One kind is the material of fibre glass, one kind is carbon fiber material. And the value of these two kinds of high-powered composite material is relative taller. “ because this, develop a kind of function to upright to be mixed at fibre glass between carbon fiber, use sex price is compared tall, high grade, can the trend ” that the new data that batch uses is development of blade composite material. “ is major to home manufacturer, carbon fiber is expensive stuff. In blade cost of infuse carbon fiber is high, craft difficulty is greater. In the meantime, current and character, lamina of manufacturing carbon fiber still is put in certain difficulty. Hua Wei of Liu of assistant of CTO of center of technology of limited company of group of development of science and technology of cable of wind of ” Shanghai moxa man says. In addition, those who not allow to ignore is, at present presence of composite material business takes inadequacy and research inadequacy seriously to composite material craft. With abroad posture of business of advanced composite material is compared, capability of innovation of business of homebred composite material is not strong, lack relevant research to the respect such as the character of material, craft, regulations that make. 　 of bottleneck of technical innovation breakthrough is aimed at homebred wind report a lot of problem that composite material exists, how to promote its function, stability, reduce cost? The application that “ should consider how to enlarge material of homebred carbon fiber to go up in wind report lamina. ” composite material learns secretary-general Zhang Boming to say, in recent years, carbon fiber is in what develop flourishingly to erupt in the application on industry condition type increases a current, but application of carbon fiber material is given priority to with foreign product, material of homebred carbon fiber applies urgently dilate and broken bureau. Carbon fiber makes an enterprise need to develop the carbon fiber that has cost competition ability to manufacture a technology as soon as possible. In the meantime, blade manufacturer, overall the manufacturer should cooperate with production enterprise of homebred carbon fiber, replace foreign product with product of composite material of homebred carbon fiber, this develops special key continuously to the industry. Zhang Boming still thinks, the fundamental trend that composite material industry uses on wind report is the application of automation production technology. Composite material automation makes technical promotion and application, can reduce production cost, shorten manufacturing cycle, improve product quality. In addition, applied craft still has a lot of, for instance automatic shop is put, the technology such as aftertreatment, automatic burnish. Xia Xiaolin expresses, to get used to blade large the industry challenge that turns development trend and cost year after year to drop, need the composite material of angle exploratory study that industry business improves from material iteration, craft, the property that promotes material, reduce manufacturing cost. For instance, promote the mechanical function of polyurethane, fatigue property further. Zhu Jingchun puts forward, the industry should drive innovation of composite material technology to tackle key problem ceaselessly, increase the high-powered data innovation in wind report domain and application, press the wide application of carbon fiber composite material, ensure the stability of blade.
