VAP®
Das von der AIRBUS Defence and Space GmbH (ehem. EADS) patentierte VAP®-Verfahren nutzt die Eigenschaften moderner semipermeabler Mem- branesysteme in hochentwickelten textilen Verbünden, um ein Vakuum über die gesamte Bauteiloberfläche zu erzeugen. Dieser „Vacuum-Assist“ stellt sicher, dass Luft- und Gaseinschlüsse während der Harzinfusion zuverlässig und effizient abgesaugt werden.
VAP® Funktionsweise
The Vacuum Assisted Process (VAP®) is a method for manufacturing fiber-reinforced plastic components using vacuum injection. VAP® utilizes membrane-assisted low-pressure infusion technology.
In this process, the component to be infiltrated is covered by a gas- and air-permeable microporous membrane, which acts as a resin barrier. The pore size of the membrane is selected to allow gas and air to escape unhindered into an outer chamber located outside the membrane, where a vacuum is maintained.
Resin injected into the membrane is retained by it and remains in the injection chamber.
VAP–Vorteile
Simple implementation; existing tools and materials can be reused.
Hervorragende Qualität der Bauteile, ohne „Dry Spots“.
Excellent quality of components, without "dry spots".
Niedrige Porosität im Laminat infolge der Entgasung über die VAP® Membrane während und nach der Infiltration.
Avoidance of resin residue; the required amount of resin can be calculated in advance.
Achieving homogeneous fiber content through uniform vacuum across the entire VAP® membrane surface.
No variations in component thickness within the workpiece.
Process robustness is improved because the gating strategy is no longer as critical.
Shorter cycle times based on the faster, vacuum-assisted infiltration process.
Higher levels of component integration are achievable.
Stable and regulated process, offering high reproducibility and reliability.
Improved cost-effectiveness, especially compared to autoclave processes.
Minimal investment required.
