Abstract

The article presents the results of a study of the operational properties of the VTP-1V grade material, including cold flow. It was found that the material of the VTP-1V grade hasn’t cold flow and, according to the complex of properties studied in the work, can be recommended as an alternative to layered polymeric composite materials used in the bolted joints of the aircraft wing rib. The possibility of operating VTP-1V in an environment of aggressive liquids was assessed and it was shown that the material is resistant to the effects of TC-1 fuel, including retaining low deformability under prolonged loading.
