English term or phrase: bleeder ply
The bleeder ply allows air to escape from the repair. It also collects excess resin. As a rule the thicker the composite plies the more bleeder plies are required

"Vacuum Bag Materials
Repairs of composite aircraft components are often performed
with a technique known as vacuum bagging. A plastic bag is
sealed around the repair area. Air is then removed from the
bag, which allows repair plies to be drawn together with no
air trapped in between. Atmospheric pressure bears on the
repair and a strong, secure bond is created.
Several processing materials are used for vacuum bagging
a part. These materials do not become part of the repair and
are discarded after the repair process.

Bleeder Ply
The bleeder ply creates a path for the air and volatiles to
escape from the repair. Excess resin is collected in the
bleeder. Bleeder material could be made of a layer of
fiberglass, nonwoven polyester, or it could be a perforated
Teflon® coated material. The structural repair manual
(SRM) indicates what type and how many plies of bleeder
are required. As a general rule, the thicker the laminate, the
more bleeder plies are required."
