AI Technical Summary

Technical Problem

Existing coupling assembly technologies using adhesives with curing times are inefficient, leading to decreased productivity due to the need to fix installation tools during polymerization, and cross-linked elastomer seals may compromise the integrity of the adhesive layer if removed prematurely.

Method used

A coupling assembly using a non-crosslinked mastic bead compressed between elements, which is adhesive and conformable to surface irregularities, allowing assembly with a vacuum application to maintain the seal without waiting for adhesive curing, and a seal volume protected by the mastic bead.

Benefits of technology

Enables efficient assembly without fixing tools during adhesive curing, maintaining the seal and protecting the adhesive from external environments, allowing immediate reuse of assembly tools.

Abstract

The present invention relates to a bonded assembly comprising: a first element (4;24) having a first bond surface (4a;24a); a support zone (4b;24b) surrounding the first bond surface; a second element (6;26) having a second bond surface (6a;26a); a non-crosslinked mastic bead (12) surrounding the first and second bond surfaces (4a, 6a;24a, 26a) and compressed between the support zone (4b;24b) and the second element (6;26); and a curing adhesive (8) in contact with the first and second bond surfaces, the curing adhesive (8) being isolated from the outside by a seal including the non-crosslinked mastic bead (12).
