VAP® Components

VAP® components:
Design. No limits.

VAP® (Vacuum Assisted Process) technology is an aerospace industry-wide standard for manufacturing of highly stressed structural components. It gives engineers the necessary degrees of freedom to implement complex 3D geometries. Tooling costs are kept at a minimum by using flexible vacuum structures.

EFW uses VAP® (Vacuum Assisted Process) technology for manufacturing of A350 VAP® beams for A350XWB.

VAP® components: general characteristics

  • Highest degree of design freedom for 3D geometries
  • Wide range of potential applications: e.g. aviation, transportation, medical purposes
  • Engineering and manufacturing services certified by EASA 21J and 21G

VAP® at EFW: state-of-the-art manufacturing

  • Single unit production of carbon fibre reinforced plastics as well as large scale manufacturing
  • Real time production monitoring during every step of the VAP® infiltration
  • On-line monitoring of all key process indicators (vacuum, resin and tooling temperature etc.)
  • Automated weight controlled resin infusion (+/- 5g per infusion)
  • Fully integrated into existing ERM (Electronic Resource Management) system at EFW

VAP® manufacturing at EFW unites all advantages of VAP® technology with the cost savings of an efficient serial production. We use state-of-the-art planning and management systems to ensure a stable manufacturing output with currently 150 different part numbers for A350XWB Programme.

The A350 combines passenger comfort, cutting edge technology, unique industrial process and environmental sustainability.
