New technology to make aeronautical composites without fear of lightning

Cost-effective fiberglass mesh fabric

Following the study of Nanocomposites with the National Center for Nano-Science, the Airbus (Beijing) Engineering Technology Center has joined hands with AVIC industry to explore the use of new technologies to improve the conductive properties of composites.

This new technology is known as “interlayer functionality”. Recently, the Airbus (Beijing) Engineering Technology Center and AVIC Industry in AVIC Composites Co., Ltd. signed a cooperation agreement to improve the toughness, damage resistance and electrical conductivity of composites by developing this technology, thereby reducing the damage caused by lightning strikes to aircraft. In fact, lightning resistance is also the main application research direction of nanocomposites at the present stage.

Today, the application of composites on civil aircraft has become one of the criteria for measuring the advanced nature of aircraft. Compared with metal materials, carbon fiber composites have many advantages, such as designability, higher specific strength and specific stiffness. Since the 60 ‘s, the use of composite materials on airliners has been increasing after decades of development, and gradually replace aluminum alloy and become the body’s main structural materials.

Today, the application proportion of several new models of composite materials that civil aircraft manufacturers have introduced has reached more than 50% of. Among them, the proportion of composite materials used has reached 53% in the body structure of Airbus A350XWB aircraft. It is currently the highest proportion of the use of large civilian aircraft.

But composites also have disadvantages. Cheng Long, general manager of Airbus (Beijing) Engineering Technology Center, said that composites have poor conductivity and damage resistance. So there are great safety risks when they encounter lightning strikes. To this end, manufacturers will add a layer of metal protection mesh to the surface of the fuselage to help conduct electricity in the production, which invisibly increase the weight of the fuselage and affect the economy of the aircraft. “We want to develop appropriate solutions on the basis of existing regulations.”

In view of this problem, the team of Professor Yi Xiaosu from AVIC Composites Co., Ltd. has innovatively put forward the concept of Interlayer Function. This technology can replace the anti-lightning metal protection mesh on the traditional aircraft, which makes the composites have good electrical conductivity and damage resistance, so as to successfully avoid lightning and anti-ice.

In the early stage of scientific research, the Airbus (Beijing) Engineering Technology Center will carry out engineering testing of Interlayer Functional technology. Cheng Long said the Airbus (Beijing) Engineering Technology Center hopes to begin testing the materials next year. The test will take place in normal flight and simulated state. “But this technology will take a long time from laboratory research and development to practical applications. It will not only to meet technical standards and evidentiary requirements, but also to minimize production costs, so as to achieve large-scale industrial production.”

Cheng Long also said that the project on “Wing Morphological transformation” is currently implemented in Airbus (Beijing) Engineering Technology Center except projects about nanomaterials, 3D printing and conductive composites. This means that the aircraft does not need to use an actuator to change the shape of the wing, which can be achieved by electricity. The benefit of this solution is very great. “Changes in the moving way can save a lot of time, especially in the maintenance of the aircraft. In addition, because of the reduction of the operating system, the aircraft can further reduce weight, thus improving operational efficiency. “

Glass Fiber Market Outlook Report

Glass Fiber Market Outlook Report

According to the Asian JEC Gazette, we have learned about the prospects of the glass fiber tube market. China’s composites market is already one of the world’s largest composite materials markets, reaching 1.5 million tons in 2007, ranking third in the world, after the United States (2.8 million tons) and Europe (1.9 million tons).

In molding technology, The obvious difference between China’s composites industry and North America and Europe is that China still focuses on hand made craftsmanship, accounting for 35%-45%, while North America and Europe are 15%-20%. The injection molding process of China is still underdeveloped, accounting for only 15%-20%, while North America and Europe are 45%-50%.

In the next five years, China’s composite materials market will grow at a high rate, with an annual growth rate of about 8%-9%. The per capita consumption of composite materials in China will increase from 1.2kg in 2007 to around 2kg in 2013 (European per capita consumption in 2013 is 3kg-4kg). Between 2007 and 2013, China’s composite materials are expected to grow in the construction and capital construction sectors (accounting for 39% of future growth), and the automotive sector is also strong (16%), followed by pipeline manufacturing (13%).

China’s demand for fiberglass and resin can be fully met by local production. In glass fiber, there are domestic manufacturers, such as Jushi, Chongqing International and Taishan Fiberglass (accounting for 60% of the country’s existing production capacity), as well as international manufacturers, namely PPG and OCV (accounting for 11% of the Chinese market).

The Chinese market will still be driven by the shift in manufacturing. For example, in China’s fiberglass market, international manufacturers are planning to develop their capacity, from 300,000 tons in 2008 to 600,000 tons in 2012. However, this growth is limited compared to the expansion plans of domestic manufacturers (from 1.6 million tons to 2.8 million tons). 2012 World Fiberglass Top 5 Production Capacity in China (10,000 tons): Jushi: 150; Chongqing International: 70; Taishan Fiberglass: 60; PPG: 37; OCV: 20.

Chinese fiberglass manufacturers will also be adversely affected by the global economic downturn. Due to the global decline in demand for fiberglass, they may temporarily freeze their investment in new capacity. However, compared to Western manufacturers, this does not substantially affect their cost competitiveness (high yield, economies of scale, lower average labor costs, etc.). Short-term demand for glass fiber is sluggish, and inventory pressure is high. Before the financial crisis, the global supply and demand of glass fiber was basically balanced. In 2001-07, the global compound growth rate was above 8%. The growth rate of China’s demand was significantly higher than the global level. In 2001-2007, China’s compound growth rate was above 23%, it is expected to maintain a growth rate of 15% in 2008-2012. Affected by the financial crisis, short-term demand has declined significantly, and only in the field of wind power has increased, and domestic demand is difficult to make up for the gap. The characteristics of glass fiber products that can not be stopped and limited production have increased short-term inventory pressure.

The industry is at the worst moment, waiting for the economic recovery. The current volume and price of the glass fiber industry are falling, the inventory is high, and the industry is at the worst moment, which is conducive to eliminating backward production capacity. However, the glass fiber industry is highly concentrated. The world’s six major suppliers (Jushi, OCV, Chongqing, PPG, Taishan, Johns Manivel) account for more than 70% of the world’s production capacity, and the application of glass fiber is extensive, and new application areas are also being developed, the economic recovery will usher in a huge rebound in industry earnings.

Comparison of composite materials industry in China and India

Comparison of composite materials industry in China and India

China and India are the two most populous countries in the world, accounting for 18.9% and 17.6% of the world’s population, respectively. China is the country that produces the most composite materials, but the composites production of India is 10 times less than China.

According to China Fiberglass Industry Association and China Composites Industry Association, China’s composite materials production reached 4.33 million tons in 2014, an increase of 5.6% over 2013.

In this growing trend, the growth rate of thermoplastic composites exceeds that of thermoset composites, following global trends. Thermoplastic composites accounted for only 27.7% of the market in 2010 and reached 37.2% in 2014. In 2014, thermoplastic composites increased by 17.9% compared to 2013, while thermoset composites only increased by 0.4%.

China is the largest producer of glass fiber (glass fiber reinforced materials) for composite materials in the world. In 2014, its output reached 3.08 million tons, an increase of 8.07% over 2013. In 2014, the export volume of China’s glass fiber reinforced materials was 1.29 million tons (up 8.35%), and the import volume was 245,000 tons (up 5.11%), so the actual domestic consumption was 2.03 million tons (up 7.4%). Since the increase in consumption is less than the increase in production, the export volume has increased.

The carbon fiber market situation in China is quite different. Except for four or five “first-class” manufacturers that are of concern to the Chinese government, most other carbon fiber manufacturers cannot produce sufficient quantities of carbon fiber with stable quality. According to the above association, China’s carbon fiber production in 2014 was 3,200 tons, and the amount is estimated to be 15,000 tons.

India began producing composite materials in 1962, reaching 314,000 tons in 2014. This market is far from stable and still faces economic uncertainty.

In 2014, the output of glass fiber reinforced materials in India was 87,000 tons, and the export volume was 11,000 tons and the import volume was 43,000 tons. Therefore, the actual consumption was 119,000 tons. Unsaturated polyester resin production was 225,000 tons, of which 143,000 tons were used for composite materials.

More than 1,200 companies in India are involved in composite materials, which are basically located in southern India. The main manufacturing process for composite materials is hand lay-up, which accounted for 42% in 2014. Other processes such as winding and pultrusion have continued to grow. The number of winding machines has increased five times in five years, slightly over 100, and the number of pultrusion machines has increased four-fold to about 100.

The six largest composite applications of India are transportation, construction and construction, electrical and electronic equipment, infrastructure, chemical anti-corrosion, and wind energy, which in turn account for 19%, 15%, 14%, 13%, 13%, and 12%. Thermoplastic composites account for only 11% in India.

Although not clear yet, the growth potential of composite materials in India is huge. This is reflected in India’s demand for infrastructure, water treatment systems and energy production. The agricultural and marine sectors are also receiving attention. Furthermore, the Indian government wants 30% of all its aerospace and defense equipment to be produced locally.

Glass Fiber Market outlook

Fiberglass is the main reinforcing material in the composite industry. In the US fiberglass market, it grew by 4% and reached 2.1 billions dollar at 2017. The market is expected to raise to 31 billion pounds by 2023, with a composite annual growth rate of 3.4%.

The world’s first e-glass fiber glass “composite” passenger lift was born

The world’s first e-glass fiber cloth “composite” passenger elevator, the elevator weight loss of 90% than traditional passenger elevator.

On January 10th, the opening ceremony of the world’s first e-glass fiber cloth composite passenger elevator was held at the hotel ,Singapore Lift Company(SLC). The elevator, known as “8”, has successfully built by a Singapore-based joint venture between the Far East agency, Woh Hup and the holding company Pronus (HK). Singapore Lift Company (SLC) .its weight is about 90% lighter than the traditional steel elevator, but carrying capacity is about doubled.The elevator is made of e-glass fiber cloth, carbon fiber and aluminum alloy honeycomb panel made of light weight, high strength, strong corrosion resistance, so as long as the appropriate maintenance, life can be up to sixty or seventy years.

SLC Managing Director Alister JA Bennett said,The use of e-glass fiber composite materials is not new, like the Boeing 787 Dreamliner and some BMW series of cars, all in the production process using such materials, but the use of e-glass fiber composite materials manufacturing elevator is a pioneering work.

“The advantages of e-glass fiber composite materials, including lightweight high strength, relative to steel, e-glass fiber composite materials is more corrosion-resistant, so as long as appropriate maintenance, e-glass fiber composite material’s life can be as long as sixty or seventy years.”

The weight of the e-glass fiber composite elevator “8” is about 150 kg, Compare with a traditional elevator the ratio is about 1500 kg, equivalent to only 10% weight of e-glass fiber composite elevator. General elevator can only carry about six people, but “8” ‘s carrying capacity can be 11 people, its carrying capacity can up to 825 kg.

Alister JA Bennett said,The traditional elevator T-type rails need to set a support point every 1.5-2 meters, otherwise the rail will bend, so the elevator shaft need a concrete wall or steel frame, so that the elevator rail bracket has a fixed place.

After we redesigned, ‘8’ do not need to use this complex elevator shaft and support frame, and lighter, so we do not have to install the balance hammer. In this way, the space saved allows us to expand the area of the elevator’s car. ”

In addition, the “8” elevator car will have a turning diameter of at least 1.4 meters, leaving enough turn space for the wheelchair. “8” is currently aimed at low-rise buildings, but the future can be extended to 20-storey buildings.

Alister JA Bennett also mentioned that the traditional elevator takes 5-7 days to complete a layer of installation, but the “8” installation process will be shortened to install at least one floor every day elevator, during which no need to use heavy equipment or welding.This will improve staff productivity and help reduce overall building spending.”

It is expected to begin selling in the third quarter of this year

“8” elevator design concept has been approved by the European elevator and escalator safety certification body Liftinstituut. Alister JA Bennett revealed that they had begun negotiations with the Construction Bureau for “8” certification, followed by an authorized elevator inspector to conduct a relevant review. “We plan to complete the certification in March and start selling the lift in the third quarter of this year.”

Alister JA Bennett said that they intend to produce “8” elevator cars in Singapore and hope to work with local universities to further improve the design and engineering of elevator components and promote the development of the overall composite industry.
 
A spokesman for the Far Eastern Agency and the Hopewell Construction Company said that “8” has the potential to meet the challenges of high cost and limited manpower faced by the local construction and construction industries. They will also assess the feasibility of adopting “8” in development projects in the future.
