DJT Carbon is buzzworthy at the Guangzhou Composites Show

Guangzhou Composites & Products Exhibition 2019, the largest composites industry trade event in southern China, was held on April 9 to 11 at Nanfeng International Convention in Guangzhou, China. There are 93 exhibitors at the 2019 event, representing every link in the composites industry’s supply chain, including raw materials, machinery and tooling suppliers, as well as fabricators and important end market OEMs.

We DJT Carbon were at the exhibition at stand A14, we mainly show our carbon fiber tubes and carbon fiber plates, also some parts made by bladder molding technique, the domestic market has a greater and greater demand for these kind of carbon parts, especially for photographic equipments, sports equipments, UAVs, robots, medical equipments.

The Guangzhou Composites Show is very effective, visitors are professional with great interest in our carbon fiber products, three customers placed sample order from us then and there, many visitors expressed the willing of visiting DJT Carbon factory after the show. According to the feedback from the organizing committee, there are 5169 visitors in total.

China carbon fiber materials will develop in a fast speed in the next ten years

Deputy Secretary of China national new material Industrial development strategy advisory committee professor Li Kejian predicted that the next ten years is the ten years when China's carbon fiber material reaches a new development height. 

When the hood of an ordinary steel automobile was hit hard by a hammer, the painted cover will normally be sunken. Last year, Chinese Academy of Science Ningbo Institute of Material Technology Engineering developed a carbon fiber car. When the cover hood was hit hard, the carbon fiber composites cover just rebounded rapidly with surface intact.

This car abandoned the traditional steel structure and adopted a large number of elastic fiber materials. It can reduce 60% weight than the ordinary steel vehicle. With the same oil consumption, the car can run 50 kilometers more every hour.

In the existing high performance fibers, carbon fiber has the highest specific strength and highest modulus with excellent mechanical performance and chemical stability. It is a non magnet material but has electromagnetic shielding function.

It also has other variety excellent performances such as low density, high temperature resistance, corrosion resistance, friction resistance, fatigue resistance, high vibration attenuation, high electrical and thermal conductivity, and low thermal expansion coefficient, high X light transmittance.

Carbon fibers can be processed into fabric, mat, sheet, belt, paper and other materials. Much can be used as reinforcing material added into resin, metal, ceramic, concrete and other materials to form the composite materials.

Carbon fiber reinforced composites used as aircraft structural materials, electromagnetic shielding materials, artificial ligament as substitute materials in the human body. Carbon fiber has been widely used for rocket shell, motor boats, industrial robot, automobile plate spring and drive shaft, as well as high speed train skirts.

At the beginning of 2000, Ministry of Science and Technology has set up a soft project "development of PAN-based carbon fiber countermeasure research" in the famous national "863" plan new materials field. And Chinese well known materials scientist, Shi Changxu was appointed as the soft group leader.

In January, 2003, China National Natural Science Fund Committee approved two key projects in the carbon fiber segment funded by the "macro-control funding". In 2005, the carbon fiber project was approved as a national key basic research project that gained valuable basic research funds.

When carbon fiber technology made progress and the industrialization has started, Shi Changxu immediately put the carbon fiber application on the agenda. He strived for special funds to support the research on the related applications and important achievements have been made.

Li Kejian said, China's carbon fiber industry has achieved initial success. At present, China has achieved carbon fiber production line equivalent to the T300 of Japan. Some enterprises have formed above T700 hundred tons production lines. China has found the breakthrough point in carbon fiber, the development will be very fast in the next ten years to come.

The Chinese government is determined to develop a first domestic large civil aircraft as C919 and parts industry that will be a globally-competitive player by 2020. The development of large civil aircraft is listed as one of China's 16 major development plans in the country's 12th five – year program. So, what is going on inside COMAC and its C919 aircraft programme right now, and should western aerospace suppliers be worried, excited or both?

As ever, the inscrutable Chinese has drawn a veil of secrecy over the entire COMAC C919 programme. Little is known about the aircraft itself until recently, but what we do know is that C919 is featured with aluminum-lithium alloy fuselage, largely composite wing and wingbox etc.

The Chinese aerospace industry has long history and last experience Chinese industry had of creating a large civil aircraft was with the Y10 project some thirty years ago, which was widely believed at the time to be a reverse engineered Boeing 707.

The design of the C919 is vastly different, technically groundbreaking in a number of areas of C919 structure which is 25% composite and it is assembled differently than an traditional metallic aircraft. Any aircraft project with the magnitude of the C919 generates some very significant investment in specific tools, jigs and fixtures and other aspects of production capability. In C919 case, the nature of this investment has been characterized by the increase in the use of composite components and in the relationship between major tier one companies and the prime. The ability to manage build tolerances for large composite structures has been driven by innovation in the use of metrology, materials for tooling and in the methodology for assembly.

AVIC subsidiaries have been allocated various sections of the aerostructure. Hrbin has taken charge of largely composite wing, Xi'an has taken charge of the mid fuselage and the performance critical areas of the airframe contained in the centre wingbox, outer wingbox, wing panels, flaps, spoilers and ailerons. Hongdu and Shenyang are manufacturing the front and rear fuselage sections and Chengdu the nose section. The final assembly line for the C919 will be located near Shanghai's Pudong International Airport and is expected to be capable of producing 2 C919s monthly by 2016.The company also plans to complete the next production system rate increase to 3.5 aircraft per month by 2020.

 

First flight for the C919 is scheduled for 2014, with entry into service in 2016. This is a very similar timeframe to UAC's MS-21 and Airbus' re-engined A320neo, and a year earlier than the Boeing's re-engined B737MAX, all of which will compete with it in global markets for 150-200 seat narrow body airliners.

Asian characteristic of concentrating on the long game must be at play here. As individual aircraft system parts of C919 are there now and represent the current state-of-the-art from global leaders in the various topic areas, but how it comes together it won't all be done in one jump. C919 plan does not only centre on this aircraft being both a technological and economic success, but also is providing a foundation for the fledgling commercial aerospace sector in China.

China can produce T-800 carbon fiber material

Recently, Jiangsu Hangke Composite Materials Technology Co., Ltd., has built China’s first production line of T800 carbon fiber industrialization, and made ​​a series of independent intellectual property rights innovation, breaking the monopoly of foreign manufacturers.

According to reports, the carbon fiber composite material is a strategic material, and plays an irreplaceable role in the field of aerospace and other Western countries on China’s implementation of the ban embargo. “Jiangsu Hangke” invests 250 million yuan to construct production line with capacity of 25 tons of T800 carbon fiber.

Currently, the “Jiangsu Hangke” company is to carry out 100-ton level T-800 production line development and construction work. In next ten years, the company will become ​​a major domestic supplier of high-end carbon fiber and composite materials products.
