Airtech says that it can also be used to provide vacuum bag protection from puncture due to bolt heads. Uncured Airflex can be applied over a release film on a prepreg lay-up, where it will cure out in the early stages of cure and will then apply pressure intensification through prepreg curing stage. Alternatively Airflex can be cured out on its own at 125°C in 20 minutes and then used as a cured intensifier over prepreg lay-ups.
The benefits include: improved part quality and reduced rework; elimination of bridging and reduction of scrap; protects bags from puncture avoiding scrap parts; makes bagging complex parts easier; and cures out quickly for fast pre-moulding or can be used uncured on top of prepregs and will cure out before prepregs, then apply even pressure.
