Thermoplastic materials are getting increasing attention in the aerospace field for a wide range of applications not only related to primary structures. In this work two types of thermoplastic structures are manufactured and investigated: a L-shaped stringer used as stiffener of flat plates; a stiffened panel for aerospace applications. The panel has been reinforced using four L-shaped stringers joined to it by induction welding, an innovative technique alternative to mechanical fastening and adhesive bonding. The main focus of this work is experimentally demonstrating the capability of the welding to keep properly the loads arising from a compression test until the failure of the stiffened panel. Interesting results came out concerning the post-buckling behaviour of the adopted thermoplastic materials that exhibited outstanding load bearing capabilities.

Abstract

Thermoplastic materials are getting increasing attention in the aerospace field for a wide range of applications not only related to primary structures. In this work two types of thermoplastic structures are manufactured and investigated: a L-shaped stringer used as stiffener of flat plates; a stiffened panel for aerospace applications. The panel has been reinforced using four L-shaped stringers joined to it by induction welding, an innovative technique alternative to mechanical fastening and adhesive bonding. The main focus of this work is experimentally demonstrating the capability of the welding to keep properly the loads arising from a compression test until the failure of the stiffened panel. Interesting results came out concerning the post-buckling behaviour of the adopted thermoplastic materials that exhibited outstanding load bearing capabilities.
