PERFORATED VACUUM MEMBRANE FOR FIBRE REINFORCED LAMINATES

摘要

A composite component for a wind turbine blade is provided. The composite component includes a stack of at least one fibre layer and a membrane which has a first surface and a second surface which is an opposite surface with respect to the first surface. The membrane is arranged with the first surface on top of the stack. The membrane is perforated with openings, wherein the membrane is formed in such a way that the openings are permeable for a fluid flowing along a first direction directing from the first surface to the second surface and impermeable for a fluid flowing along a second direction directing from the second surface to the first surface.
