Abstract
Some embodiments are directed to 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.
Claims18
A method for overmolding a thermoplastic end-fitting on a hollow profile made of thermosetting composite, including:
- machining a shape of the profile made of thermosetting composite on an injection zone;
- positioning a plug in the profile member;
- thermally conditioning the assembly of the profile member, and of the plug;
- and
- injecting the end-fitting with thermoplastic composite to create a junction of the profile member, the plug, and the end-fitting.
An assembly comprising a hollow profile member made of thermosetting composite of internal diameter D1 and of external diameter D2 and a thermoplastic end-fitting wherein it includes a plug arranged inside the profile member and the profile member includes a machined part at an end of the profile member.
