Sponsored By Weihai Development, The Revised Standard Of PAN Based Carbon Fiber Was Approved.

Carbon fiber, known as "black gold", is an important strategic material for the development of national defense industry and national economy. In the revised standards issued, The classification of solvents and the classification of spinning processes have been increased, and the testing methods have been supplemented and perfected. At the same time, The varieties and specifications of carbon fiber have been increased. , And its corresponding range of performance indicators. 。

In the revised standard, the increase of carbon fiber varieties, especially the increase of high strength carbon fiber and high strength and high modulus carbon fiber, not only includes the new varieties of high performance carbon fiber in our country, but also reflects the latest achievements in the development of China's carbon fiber industry, and contains a new type of high-performance carbon fiber products that will come out in the future. The standard is advanced, forward-looking and leading. Among them, The grade of the model product corresponds to the world benchmark product level, which fully embodies the international advanced standards. 。

Insiders pointed out that The newly revised standards fully reflect the progress of China's carbon fiber technology level, especially the maturity of dry and wet technology, which promotes the engineering and industrial production of new type high performance carbon fiber products. After the implementation of the new standard, China will further standardize the domestic carbon fiber market and promote the high quality development of the domestic carbon fiber industry.

It is also worth noting that The revised standard is chaired by the Weihai development Fiber Co., Ltd., a wholly owned subsidiary of China's carbon fiber leading enterprise, hereinafter referred to as "Weihai development". 。

In recent years, the domestic carbon fiber industry has developed rapidly, and product models are constantly emerging. Against this background, the revision of national standards is imminent. In 2017, Weihai expanded the standard revision notice issued by the National Technical Committee for fiber reinforced plastics standardization, and then led the industry related production and research institutes to set up a national standard revision team to start work. After several rounds of expert opinion collection, conference discussions, performance statistics of major manufacturers, and third party tests, the revised panel submitted a revised national standard approval document in July 2019.

" At present, Guang Wei complex has presided over the 2 national standards of PAN based carbon fiber and carbon fiber prepreg, and has applied for more than 230 patents. 。 Next, we will continue to shoulder the responsibility of leading enterprises in the industry, drive technology development by technology, lead innovation and development with standards, and contribute more to the high quality development of domestic carbon fiber industry. ?
