The development of wind turbine blade manufacturers in China faces many challenges

“In recent years, the wind turbine blade industry has achieved great-leap-forward development and has rapidly formed an industrial scale in the short term. However, there is a general lack of independent innovation capability, lack of real independent intellectual property rights, production technology and raw material outsourcing, etc.” The latest research report of the scientific planning project “Semiconductor Lighting and Wind Power in Several Key Industry Technological Innovation Policy Research” pointed out that the overcapacity of low-end products and the lack of competitive high-end products will cause domestic wind turbine blade manufacturers to face new challenges.

The report pointed out that the technology of wind turbine blade manufacturing companies comes from abroad, according to foreign standards of production, raw materials imported from abroad, companies do not have the initiative to research and development innovation. Many key technologies in the test development, design and manufacturing, production process, and mold equipment of blades have not been mastered. Foreign companies are researching and developing some new technologies that improve the utilization of wind energy and increase the service life. Chinese enterprises and scientific research institutions have not yet conducted substantive research.

The analysis of the report has caused the following four main reasons: First, domestic scientific research institutions are unable to meet the needs of production enterprises; Second, the National Standards Committee has formulated and formulated leaf production standards that are still in the process of drafting revisions, and have not yet been obtained from foreign countries. Mutual recognition; Third, the backward status of domestic basic industries has not been fundamentally changed; Fourth, driven by interest factors, some enterprises, scientific research institutions, and industry sectors are eager to achieve success, and are unwilling to engage in long-term and arduous basic research and development work. There is also not enough capacity to resist the great risks caused by R&D.

The report pointed out that the condition of the wind turbine blade industry is not a case. It has a certain representation in the entire manufacturing industry. Therefore, in addition to public infrastructure construction, the state’s 4 trillion investment should focus on improving innovation capabilities in the implementation of industrial revitalization planning. The state investment is mainly applied to industrial basic research, applied basic research, key equipment development, and key technology research and development. Advanced research and advanced technology.
