A preliminary study on the development of China's composite industry during the 12th Five Year Plan period

composite materials are an important part of the field of new materials. Compared with traditional materials, composite materials have a series of superior properties, such as strong designability, high specific strength and modulus, good fatigue fracture resistance, and integration of structure and function. They are functional and structural materials that are difficult to be replaced by other materials. They are important for the development of modern industry As an indispensable basic material for national defense and science and technology, it is also an important material basis for the development of new technological revolution. Composite materials have become an important leading material in the field of new materials

development status

production status

the development rate of composite materials industry in Asia is much higher than the growth rate of the world economy. In 2009, the global output of composite materials/composites was about 9million tons, of which North America, Europe and Asia were the three largest production and application areas. The annual average growth rate of global resin matrix composites was more than 5%, Among them, the growth rate in the Asia Pacific region can reach 7% (about 9.5% in China, about 15% in India, and 4% in Europe and North America)

at present, there are about 450000 composite employees in the world, with a total output value of about 45billion euros

China's output reached 3.23 million tons in 2009, which has surpassed Germany and Japan and ranked second in the world, and is close to the level of the United States, which ranks first in the world

consumption

technical equipment the level of domestic composite equipment has been continuously improved, and a number of internationally advanced production lines have been built in succession. At present, there are 350 production lines for fiber fixed length pipes, sand inclusion pipes and horizontal storage tanks (including high-pressure pipe production lines) in China. First, carefully read the manual of electronic universal testing machine for fiber winding. There are 2 continuous pipe production lines, 2 centrifugal pipe production lines, more than 50 manufacturers of megawatt fan blades, more than 200 SMC and BMC special presses, more than 400 pultrusion production lines, more than 110 continuous plate production lines, more than 580 sets of jet machines There are dozens of manufacturers of various SMC water tanks and dozens of manufacturers of various pultrusion. By 2009, the proportion of mechanized forming of composite materials has reached 66%

raw materials

the main raw materials for composite materials have been basically matched. The quality of many glass fibers and resins has reached the international level, and the prices are competitive. Take glass fiber as an example. Since the 11th five year plan, the scientific and technological development of glass fiber industry has been encouraging and achieved remarkable results. A large number of important scientific and technological achievements, such as large-scale alkali free tank kiln technology, pure oxygen combustion technology, short cutting, electric melting aid, 6000 hole large leakage plate, new glass formula, automatic logistics line, large-scale production of multi axial fabrics for wind power, large-scale production of ultra-fine electronic yarn, have greatly improved the technical level and international competitiveness of the industry. Among them, the alkali free glass fiber tank furnace wire drawing technology has reached the international advanced level. The world's largest alkali free tank furnace wire drawing production line with an annual output of 120000 tons was completed and put into operation during the "Eleventh Five Year Plan". The technical equipment with China's independent intellectual property rights has been widely adopted in the whole industry and exported one after another

development trend

the focus of the global composite industry is shifting from developed countries in Europe and the United States to Asia. The rapid growth of composite output in Asia is one of the most obvious trends in the industry development. The output is expected to double to more than 8million tons by 2015. It is expected that Asia's share in the global composite market will increase from 25% at the beginning of this century to 51% in 2013

with the development of advanced and sophisticated technologies such as wind energy and aerospace, composite materials will be applied more in the field of high added value

China will become the most active and fastest growing region of composite materials in the world. In the next few years, with the transformation of China's economic structure, economic transformation and the rapid development of the national economy, composite materials will achieve greater development in China

India also has growth potential in composite materials that can not be ignored. The rapid development of automotive and other application fields will drive the growth of another ultimate goal of Indian composite materials industry

the Middle East, Malaysia, Vietnam and Indonesia are also countries and regions with high growth potential

the development trend of composite technology in China will show the following characteristics: the development of high-performance composites based on carbon fiber in China's plastic machinery market will accelerate; Multi process integration technology has become the inevitable trend of technology development; The design technology and software of composite materials will be improved; Innovative design and use will replace the original design idea of "alternative materials"; Low cost and low emission manufacturing technology will be emphasized; In the design, manufacturing, use and other aspects, the idea and concept of environmental protection will be widely recognized
