Carbon Fiber &Nbsp; Get Out Of The Way Of Low End Breakout (2)

In 2008, a large number of new chemical material projects including carbon fiber were included in the overall supporting projects of major aircraft projects launched in China. The carbon fiber products and carbon fiber products in various fields in China have been increasing. Many carbon fiber research projects or 1000 ton scale industrialization projects have been launched.

However, due to our country

According to the introduction, from technology research and development to

According to the prediction of relevant departments, the demand of world carbon fiber will grow at a speed of about 13% every year. In 2010, the global demand of PAN based carbon fiber will reach 50 thousand tons, and by 2012, it will reach 60 thousand tons, and the demand is expected to reach 100 thousand tons by 2018.

To this end, the world's seven largest carbon fibers

Break through the road 1: clenching fists to form a resultant force

How to rapidly upgrade the pace of upgrading China's carbon fiber industry under the prospect of supply exceeding demand? Qian Bo believes that in the domestic constraints on the development of carbon fiber, the lag of PAN raw silk level is the bottleneck restricting the production level of carbon fiber, which not only affects the quality of carbon fiber dimension, but also affects its output, production cost and market competitiveness.

At present, China urgently needs to master high performance PAN based precursor production technology and seize market opportunities.

Under the premise of improving the production technology of carbon fiber, we should make breakthroughs in the manufacturing technology of PAN based raw silk as soon as possible, develop high-quality upstream production lines, ensure the stability of carbon fiber production and product quality, thus breaking the blockade and monopoly of foreign countries in key technologies.

To this end, the major scientific research institutions and enterprises should grasp their fist to form a resultant force so as to avoid repeated introduction and duplication of research.

Qian Bozhang suggested that the support of the state should be mainly focused on the establishment of a systematic research network with different needs, while increasing investment and tax and credit policies to encourage carbon fiber production enterprises, raw material production enterprises and powerful investment enterprises, especially for the pioneering enterprises.

Although China has clear planning and target tasks for the production of carbon fiber, the phenomenon of repeated introduction and repeated research is still very serious.

The state should focus on supporting several successful enterprises, vigorously cooperate, optimize the layout, integrate resources, cooperate in tackling key problems, prevent low-level duplicated construction and blind development, and achieve the goal of making more enterprises less detours and cost savings.

Make our country a country with independent control, independent ownership of technology and industrialization development.

Qian Bozhang also suggested that we should learn from the advanced experience of other countries, strengthen the close combination of production, teaching and research, establish relevant mechanisms, and upgrade the development of high performance fiber industry to the national strategic level, so that China's carbon fiber industry can develop rapidly and healthily.

Breakthrough Road two: focus on recycling

In recent years, foreign research and development of carbon fiber technology focused on improving performance and reducing costs.

According to the demand for the development of advanced composite materials market, Japanese Dongli company has decided to phase out T300 class carbon fiber, and focus on developing carbon fiber varieties with a tensile strength of 4000 to 5000MPa and a price equivalent to T300. At the same time, because of the high cost performance of large bundles of carbon fiber, large wire bundled carbon fibers have begun to develop, such as the latest development of T6005, T7005, T700G and so on.

In addition, some enterprises attach importance to the development of environment-friendly recycled carbon fibers.

Japan's Dongli, Tei and MITSUBISHI Liyang plan jointly launch large-scale production of recycled carbon fibers to promote the recovery and utilization of high-strength and lightweight materials.

Carbon fiber products are mostly used in special fields, and their service life and renewal cycle are strictly required. A large number of waste carbon fiber products are urgently to be dealt with.

According to Japanese MITSUBISHI Liyang estimates, the world's discarded carbon fiber is about 10 thousand tons, up to 20 thousand tons in 2010.

With the expansion of carbon fiber production capacity and the increasing use of materials, the trend towards environmental friendliness requires enterprises to pay attention to the recycling and utilization of carbon fibers.

The developed countries have already started this work: the new technology developed by the German TITK Research Institute can obtain the carbon fibers of length 20mm or 30mm to 70mm from waste carbon fiber textiles without tear treatment. The INASMET pport safety agency in Spain has developed a new way of recycling and recycling carbon fiber epoxy resin composites by chemical and thermal treatment technology, and its recycling products can be used in general carbon fiber products.

In 2009, Dongli, Japan, MITSUBISHI and Li Yang set up a joint venture to recycle and recycle carbon fibers from aircraft and other equipment.

The annual output of recycled carbon fiber will increase from a few hundred tons to the world's largest production of 1000 tons.

At present, should China learn from the advanced ideas of foreign countries and incorporate the research and development scope in the recycling of carbon fiber? After all, standing on the shoulders of giants can help us see higher and farther.
