Ultra-lightweight Star-Quad data cable from Draka Fileca for the aviation industry wins third prize ...

15.11.2013 the DuPont Plunkett Awards in the EMEA Region

For the insulation of its new Star-Quad data cable KL24 for the aviation industry, Draka Fileca uses a fluoroplastic foam type instead of a conventional fluoroplastic. This allows weight savings of up to 25 percent – with the same diameter and identical transmission properties.

This has been made possible by modifying the design and using a fluoroplastic foam for the insulation. It not only helps to reduce fuel consumption in aircraft, it also lowers their environmental impact.

For this development, Draka Fileca – which is part of the Prysmian Group – took third place in the DuPont Plunkett Awards in the EMEA Region. The Plunkett Awards 2013 coincide with the 75th anniversary of the discovery of PTFE by DuPont scientist Dr. Roy Plunkett, and reward outstanding technical developments in the field of fluoroplastics. The presentation of the sculpture and the prize money of 2,500 US dollars was made by Agnès Ibos, Account Manager France at DuPont Chemicals & Fluoroproducts (CF&F), to Charles Boullot, R&D Project Leader at Draka Fileca.

For its new long-range aircraft A350, Airbus charged Draka Fileca with the development of a cable for digital data transmission. The cable not only had to enable high transmission rates but also had to be much lighter than the previously used KD24 type. Charles Boullot explains: “The challenge with developing this cable was to lower the weight without reducing the diameter, because one of the customer’s specifications was compatibility with existing contacts, connectors and tools. That is why we decided to use a fluoroplastic foam type for the insulation instead of a conventional fluoroplastic.” The type that was finally used was DuPont™ Teflon® FFR 770, which belongs to a family of new foam grades based on DuPont’s patented Airquick technology. These products are suitable for the production of lightweight high-performance cables for high-frequency signal transmission in a wide temperature range and with minimal signal distortion.

The new Star-Quad data cable KL24 from Draka Fileca complies with the requirements of EN 3375-011 for electric cables for digital data transmission in the aerospace industry. It has the same transmission properties as the previously used KD24 quad cable, but is up to 25 percent lighter. It will initially be used in the new long-range Airbus A350, and there are plans in the near future to extend it to the A380 and all other Airbus platforms.

By replacing the existing data transmission cable with the new KL24 from Draka Fileca, the weight of an Airbus A380 can be lowered by as much as 85 kg. According to calculations by the French Aerospace Industries Association GIFAS, an aircraft will thus use 510 t less fuel over its lifetime, and produce 1,700 t less greenhouse gases.

Draka Fileca, part of the Prysmian Group, has a rich heritage in delivering dedicated wires and cables for the aerospace industry. Founded more than 50 years ago, the company rapidly became a European leader for aerospace wires and cables. Since the early 70s and the Concorde program, Draka Fileca has produced, with the most innovative technologies, wires and cables for both civil, military aviation and space. Draka Fileca develops, manufactures and sells a full range of wires and cables to the aircraft and helicopter manufacturers all over the world, from airframe wires (copper or aluminium based) to data-transmission cables (copper or optical fiber). Thanks to the expertise and the know-how of their 180 employees, Draka Fileca has received during the last couple of years important distinctions from companies like Fokker, Labinal or Airbus, which gave them the award of the best supplier in 2012. Those awards recognize the excellence of the high quality and service level that Draka Fileca offers to all its customers.

DuPont (NYSE: DD) has been bringing world-class science and engineering to the global marketplace in the form of innovative products, materials, and services since 1802. The company believes that by collaborating with customers, governments, NGOs, and thought leaders we can help find solutions to such global challenges as providing enough healthy food for people everywhere, decreasing dependence on fossil fuels, and protecting life and the environment.

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...

COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.

In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...

Im Focus: Ultra-thin ferroelectric material for next-generation electronics

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.

Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
