Magnificent 70 Years, We Will Conquer The Problem Of "Necking" By Ourselves.

In the past 70 years since the founding of new China, as the important strategic material in the field of national defense industry, the development of China's carbon fiber industry has gone through a difficult and tortuous course.

The so-called "weapon of the country can not show people", the real core technology can not be bought. The carbon fiber material, known as the "black gold" material sector, belongs to the "country's most important material" which is blocked and can not be bought by the core technology and must rely on independent research and development.

Carbon fiber is a high-performance synthetic fiber, widely used in aerospace, rail transportation, wind power, energy and construction, and also an important strategic material for national defense weapon and equipment support. In 1959, Japan made carbon fibers from polyacrylonitrile based precursors and started the application of high-tech materials "black gold". In the following decades, Japan, the United States and other countries have developed carbon fiber products, and gradually occupy the 85% share of the global carbon fiber market. China's R & D carbon fiber began in the 60s of last century, but the development process of more than 30 years is full of frustrations, which seriously restricts the development of our national defense and industrial undertakings, and becomes a "neck and neck" problem.

Faced with huge financial and technological risks, Weihai Guang Wei composite material Limited by Share Ltd (hereinafter referred to as "Guang Wei complex") 2002 Started the project of carbon fiber project, after 3 years of research and development. 2005 Breach Domestic T300 class carbon fiber core technology The performance of the products has been up to standard and has become the first enterprise to realize carbon fiber engineering in China. China has also become one of the few countries in the world that master the key technology of high performance carbon fiber engineering.

Finding a breakthrough for upstream prepreg

Before researching and developing high-tech materials carbon fiber, the group of Guang Wei composite group is engaged in the field of carbon fiber fishing industry, which is closely related to carbon fiber application. Guang Wei group was founded in 1987. After 32 years of operation and development, the fishing tackle developed by Guang Wei Group has accounted for 25% of the global fishing gear market share, with an annual output value of nearly 1 billion yuan. "GW" and "light star" The two largest independent brand, at the same time, Guang Wei Group has become the largest domestic fishing gear industry with the largest capacity.

Fishing gear plays a very important role in the application of carbon fiber in the booming fishing gear industry. Because of the slow development of domestic carbon fiber technology and products, the carbon fiber and prepreg products used for fishing gear were totally dependent on imports. Because carbon fiber and prepreg were widely used in aerospace, weapon and equipment special fields, Japan and the United States and other countries strictly controlled the blockade of China. The carbon fibers and prepreg materials used in various fields in China were controlled by others. In 1998, Guang Wei Group invested 2 million US dollars in the introduction of prepreg production equipment, built the first wide prepreg production line in China, and developed various high-performance resin systems and core technology to fill the blanks of domestic prepreg products and technology, producing the first volume of China's carbon fiber prepreg in a real sense, breaking the monopoly of the US and Japan in this field at one stroke. After more than 10 years of development, Guang Wei Group has the capability of designing and manufacturing carbon fiber prepreg equipment with independent intellectual property rights. It has formed many patents and core technologies, and has built 16 prepreg production lines with an annual capacity of 25 million square meters. National standard for carbon fiber prepreg 。

Independent research and development to conquer "black gold"

In 2001, there was no significant breakthrough in carbon fiber research in China for decades. Carbon fiber is an important part of developing composite materials necessary for advanced fighters and missiles, especially for strategic missiles. But advanced industrial countries have blocked us for a long time, neither selling products nor transferring technology. Therefore, the production of high performance carbon fiber must be based on China. In twenty-first Century, if China did not have its own carbon fiber, it would lag behind the whole era. Subsequently, the Ministry of science and technology set up a special carbon fiber project. "863" expert group Invest 200 million yuan in R & D funds.

The first wide prepreg production line introduced 。

At that stage, the successful innovation of carbon fiber prepreg not only brought profits to the enterprises, but also made the enterprises have a deep understanding of the core technology innovation. In the face of strict control and blockade abroad, Guang Wei Group firmly believes in breaking the monopoly, forming its core technology and arming enterprises with core equipment. Carbon fiber, which is used for prepreg materials, is still subject to human condition. The group proposes to upgrade its original carbon fiber fishing gear and carbon fiber prepreg industry independently, and set up carbon fiber R & D project team to develop carbon fiber.

In 2003, when the national carbon fiber "863" expert group came to the field research of prepreg products, it was a casual chance to know that the "black gold", which had not been conquered for decades, was made by a company in a small fishing rod factory. At that time, there were two "national teams" participating in the carbon fiber "863" project, and the progress of research and development was stagnant. The group of experts immediately decided to work on the spot sampling, on-site sealing and testing immediately in a responsible manner. After the authoritative third party blind test and the fair evaluation, the "Wei" composite material obtained the "863" qualification. Based on the third party test and evaluation, the expert group has the best mechanical properties of the carbon fiber, and is among the best in the contest with the national team. The 2 carbon fiber "863" project is temporarily added at the fastest speed, and the 16 million yuan is also supported by Guang Wei complex. At the same time, as a national defense strategic material, we began to validate the domestic carbon fiber for military industry aviation, representing the "Guang Wei" complex "joining the army" formally.

Since 2010, the CCF300 carbon fiber produced by Guang Wei complex has entered the stable supply stage, and has become the largest supplier in the field of domestic military aviation, providing guarantee for national strategic equipment. The "black gold" developed by a private enterprise has ignited the light of the nation.

Expand the whole industry chain and enhance competitiveness

Over the past decade, the R & D has broken through the core technology of a series of carbon fibers, forming a raw silk carbon prepreg product, which is equipped with the whole industry chain research and development capacity. "National Engineering Laboratory for carbon fibers", "national enterprise technology center" and "post doctoral workstation" And other 9 national and provincial scientific research platforms. The company includes projects including "863". 80 more items Presided over PAN based carbon fiber and Carbon fiber prepreg Two national standards for patent application 338 items Authorized patents 182 items ; get "National high technology industrialization ten years achievement award", "national science progress two prize". And many other awards.

Our company has already mastered the wet process, dry spray wet spinning process, and can produce high-strength, high model, high strength and high modulus carbon fiber. The products can meet the demand of independent supply of carbon fiber materials in the field of military industry in China. It can not only produce a series of high-strength series carbon fiber, high modulus series carbon fiber, but also produce large tow carbon fiber. At the same time, in recent years, Guang Wei composite has made great efforts in the civilian field, and has become an important supplier of the global wind power giant "guestas wind power carbon beam", and civilian business has also become an important support for the company's performance.

At present, Guang Wei complex has built up a multi-dimensional, three-dimensional military civilian product collaborative development mode on the road of independent development of domestic carbon fiber. It has built up a scientific research and production platform for the whole industry chain, formed a sustainable healthy development ability, stepped into a benign development track, and enhanced the comprehensive competitiveness and profitability of the enterprise, and stepped out of an independent innovation of China's "black gold" high quality development road.
