Boeing has selected Japan’s Toray Industries to provide Torayca prepreg composites for use in the primary structural areas of Boeing’s new long-haul passenger aircraft, the7E7 Dreamliner.
“Composites offer us a variety of advantages including better durability, reduced maintenance requirements and increased potential for future developments,” said Mike Bair, senior vice president — 7E7 Program. “Toray’s composites will make the 7E7 light, strong, and extremely reliable.”
The composite prepreg material, a combination of high-strength carbon fibre and toughened epoxy resin, has is said to have proven performance on 777 structural applications such as the empennage and floor beams.
The composites will be used in major sections of the 7E7, including the wing and fuselage. Toray, the world’s largest manufacturer of polyacrylonitrile-based carbon fibres, will supply the composites material from its facility in Tacoma, Washington.
