How hybrid moulding has changed the game in aircraft component design

Continuously reinforced composites and lightweight polymers are taking the Aerospace industry by storm. For several decades, engineers have had to make the choice between the two when looking for metal replacement solutions…but what if you didn’t have to choose?

Hybrid moulding or overmoulding allows engineers to take advantage of the strength of the composite whilst enabling complex designs and processing flexibility through injection moulding polymers. Now, you may be thinking that you have seen something like this before, and the truth is that you probably have.

Lower-Melting PAEK Composite Technology

The differentiator with the Victrex hybrid moulding technology is that this is the first time a PAEK-to-PEEK bond was achievable. The enabling material technology, VICTREX AE™ 250 composites, offers a lower processing temperature than standard PEEK composites which supports the fusing of the composite with the injection moulding polymer.

Avoiding costs whilst speeding up production

The new composite product can be processed on conventional equipment typically used for PPS or PEI polymers so no need to invest beyond existing infrastructure. Moreover, the lightweight, reliable material can help speed up the overall production of aircraft.

Admittedly that would still not be sufficient reasons for today´s aircraft designers to fully jump on a new solution. But how about designers being able to design a component that:

  • Has a strength-to-weight ratio that rivals or surpasses metals
  • Can be produced in a matter of minutes and requires no secondary processing
  • Enables part consolidation and optimization to help speed up installation
  • Can reduce costs via economical processing and is fully-recyclable

This is what hybrid moulding with VICTREX AE 250 composites and VICTREX PEEK polymers can offer in applications ranging from clips and clamps to brackets and assemblies for aircraft interiors, engines, fuel systems, and beyond.

Designing to full potentials

Challenging the status quo can result in finding a better alternative to metals or thermosets and allow designs reach their potential. The various performance and processing benefits that hybrid moulding provides for the entire value chain are explained in a video.
