Application of Synthetic Diamond Composite Material in Aeronautic Equipment

With synthetic diamond technology being mature gradually, the application of diamond materials’ reinforced plastic in the field of aeronautic equipment is becoming more and more widely and deeply. Aviation Power Department of Element Six express that in the next generation solution of 3D composite tools, the productivity of carbon fiber reinforced plastics (CFRP) will be increased by three times.

As synthetic diamond manufacturer and branch company of DE Beers, Element Six has established aerospace PCD product portfolio Aero - Dianamics ™. Compared with the cemented carbide cutting tool system, new series of products can improve the production capacity per unit of product parts (three times or so) and reduce the manufacturing cost, especially CFRP composites processing.

At present, CFRP materials account for about 50% of the whole fuselage material. Taking Boeing 787 dreamliner for example, we can find that CFRP materials have been applied to fuselage, aerofoil, empennage, stabilizers, control surfaces and nacelle, etc. And for airbus, they have accounted for more than 53%. The demand for this material will be expected to grow at 14% a year in the future application in the aerospace industry. And in the field of automobile manufacture, composite materials will have higher growth rate.

CFRP materials that can promote the economic development of aerospace industry, have the following advantages:

Aircraft’s reduction in weight can improve the emission technology, thus improving fuel efficiency about 25%.

It can improve and introduce new technology, like the following generation new turbine.

It is durable and can reduce maintenance costs.

It can improve the strength of aircraft performance, thus improving cabin pressure and passengers’ comfort.

It can improve the payload.
