Manufacturing Route for Hot Stamping of Aluminium Alloy Applied to a Wing Rib

In this study, a hot stamping process, which delivers ready-to-use parts for the production of aircraft components is applied as an alternative manufacturing method to, for instance, machined parts. The research has been focused on examining the formability of an aluminium alloy at high temperatures. An extensive experimental campaign has been conducted to establish the optimal hot stamping process parameters. As a final stage of the development, a demonstrator corresponding to a wing rib with AA2198 aluminium-lithium alloy has been successfully produced. After the corresponding heat treatment, material properties have been restored.
