  • Hollow profile member such as a tube made of thermosetting composite materials and corresponding method
    Patent number: 10987836
    Abstract: A method for overmolding a thermoplastic tip onto a hollow profile member made of thermosetting composite and to an assembly including a thermosetting profile member and a thermoplastic tip, wherein it includes machining the shape of the profile member made of thermosetting composite on the injection region; positioning a cap in the profile member; thermally conditioning the profile assembly and the cap; and injecting the tip with thermoplastic composite in order to create the junction of the profile member, the cap and the tip.
