Compared with traditional industries, carbon fiber high-tech enterprises have higher thresholds, more investment, and higher risks. However, they have large markets, high profits, and good prospects. The state encourages them. In view of promising industrial development prospects, a large amount of domestic capital has poured into this industry in recent years. After nearly ten years of hard work, China's carbon fiber industry has initially cleared the doorway, preliminary technical research, initially possesses the industrial scale, the initial level, and initially meet the needs of the national economy and social development.

Jiangsu is a major province for industrial development. Various new industries and new industries will find production companies in Jiangsu, from the former photovoltaic industry, graphene industry to the carbon fiber industry. Among the country's more than 30 carbon fiber companies, there are nearly 10 in Jiangsu, accounting for a quarter. At present, China's four major carbon fiber companies, Jiangsu Hengshen, Zhongfu Condor, Blue Star, and Weihai, which have built up a kiloton production line, have Jiangsu Jiangsu Hengshen and Zhongfu Shenying. Some other carbon fiber enterprises in Jiangsu include Changzhou's Jianzhong Science and Technology, Zhenjiang's Jiangsu Hangke, Jiangsu Zhongke, Jiangsu Wuxi, Jiangyin, and Yixing with some carbon fiber fabrics.

Observe the development of the carbon fiber enterprises in our province and our country and analyze their strengths and problems. We can easily develop them. The five major challenges faced by the nation's carbon fiber production can be found in some companies in Jiangsu or China.

Technical Bottleneck: It is necessary to explore each other but also to coordinate research

Needless to say, the backwardness of technology is the fundamental reason for the lack of competitiveness of domestic carbon fiber. At present, the production of carbon fiber is not difficult, it is difficult to be in the stability of the product and the acceptability of cost, release production capacity, and achieve stable production. To achieve these goals, the most pressing issues that need to be solved are:

1. How to ensure product quality from the optimization of manufacturing equipment.

The transition from non-standard production lines to standard production lines is a prerequisite for ensuring product quality. The debugging of the process parameters needs to be realized by manufacturing equipment. The process parameters are input on the controller. Several rollers on a tractor are required to adjust the speed. The key is micro-vibration. The almost undetectable vibration will affect the product performance. Dry jet wet spinning process, the distance between the spinneret and the liquid surface is very strict, liquid level fluctuation will affect the solidification effect.

2. How to ensure the quality of the product accurately from the process parameters.

The process parameters are the lifeblood of domestic carbon fiber, and it is necessary to really set the mind to study each of these parameters. The number of defects caused by one parameter is not large, but many parameters are not optimized, and the final carbon fiber is tens of thousands of miles away. Also, if we want to optimize many of these parameters, we need a huge pilot program. Who can have funds to support these experiments? In order to make products as early as possible, they are constantly making compromises and compromises. As a result, they cannot produce good products.

3. How to ensure product quality from stable and even production.

Many of our companies are able to make carbon fibers known as T300, T700, T800, and T1000 levels, but not too uniform. A single fiber should have a uniform diameter and a uniform phase. Each piece of fiber has the same strength as the entire fiber and its strength is within a certain range. A section of fiber is cut in different places on one fiber and is a good fiber if their strength is relatively uniform. This is a temporary goal, and our effort is here.

Due to the foreign technology blockade, the technological breakthrough in the development of carbon fiber industry is the first problem that every company must face. Not only is it blocked abroad, but also the technologies of various carbon fiber companies in China and the province are groping and blocking each other. Due to technical and technological problems, companies have not only paid a heavy tuition fee, but also spent a long time. The process of mass production, stable production and industrialization has been severely constrained. At present, although some carbon fiber enterprises have initially mastered the industrialized production technology of T300 carbon fiber, they have basically mastered the industrial production technology of T700 grade carbon fiber. However, due to the fact that the carbon fiber production line is frequently used for several hundred meters, it is extremely complex. The parameters such as temperature, humidity, speed, and force can influence the quality of the carbon fiber precursor and carbon fiber. Compared with developed countries, we still have a big gap in product stability, reliability, and economy. The industrialization technology of high-end products is still blank. In order to speed up the localization process of carbon fiber and shorten the period of breastfeeding for carbon fiber enterprises, it is recommended that national or provincial development and reform commissions and science and technology departments should join relevant universities to set up a technical synergy research group to make breakthroughs on the key technical problems that restrict carbon fiber companies, and each key carbon fiber enterprise Leading one of the main problems, after sharing, benefit sharing.

Disclosure of Results: It is Necessary to Speak and Speak

Although carbon fiber technology is mature and difficult to upgrade, it is a long way to go, but we can often see the disclosure of technological breakthroughs in carbon fiber companies around the world.

As a person in the carbon fiber industry, we understand that every breakthrough in carbon fiber technology is very difficult and it is worth congratulating. However, we must constantly remind ourselves that science is science and science must be practical and realistic. It must not be false at all. To this end, it is necessary to conduct checks on the release of carbon fiber results, and through the demonstration of relevant departments, establish an authoritative release system and establish a fair and authoritative release of information.

Steady Development: Both Output Quality and Consumption Loss Reduction

Carbon fiber companies have been driven by the demand for new materials and encouraged by the national industrial policies, which have attracted capital investment. They know that there are tigers in the mountains and tend to be in favor of Hushan Bank. While improving quality, the output of the carbon fiber companies is also rising. However, because foreign countries have implemented multiple monopolizations of technology, market, and prices in China, the difficulty of solving the costs is even harder than the previous technical problems.

In the past, because of the military value of carbon fiber, western countries have been very tightly guarded against our country. In the past, it was primarily a technology blockade for China that did not transfer technology or sell equipment. However, following the series of difficulties in independent research and development in China to overcome production technology and production equipment and open the localization of carbon fiber, manufacturers in Japan and the United States began to In the article, the carbon fiber industry was greatly suppressed, so that the entire industry suffered losses and faced a great crisis of survival.

According to industry sources, when we heard that China needs a certain type of carbon fiber but can not produce its own products, foreign companies will pay a price premium; when China's product quality and sales have improved, they will dump the market regardless of the cost of low prices, resulting in our country. Carbon fiber companies have been forced to cut production significantly and stop production, so that they cannot reduce costs and improve quality in continuous large-scale production.

The cost reduction can only solve the fundamental problem through energy conservation and consumption reduction. This requires the joint efforts of the national, provincial, and local governments to provide corresponding support funds to help the carbon fiber company to cultivate and cultivate Guyuan and to survive the winter.
