Russian manufacturers developed an all-composite airframe for advanced fifth-generation PAK FA fighter, ARMS-TASS reports with reference to a source close to Rostech Corporation.
"PAK FA is made of composites: airframe, wing and empennage. The components are manufactured by a company of RT-Khimcomposite Holding", - the source said.

He also said that the basis for production of composite components in Russia was created in the network of development of legendary Soviet Energiya-Buran reusable space system. A development center was established in Obninsk in order to develop technologies for manufacturing components made of polymer composites. It had state-of-the-art equipment, used the latest technologies and had high-skilled personnel. Development of new materials set new tasks for the scientists.
