The invention describes a method of preparing a mould having a moulding cavity surface with vacuum flow topology for vacuum resin transfer moulding. This method comprises the following steps:
- pressing a number of peel ply layers into an uncured resin layer for building up the moulding cavity surface,
- curing the resin of the resin layer, and
- detaching the peel ply layers to generate the vacuum flow topology in the moulding cavity surface. The invention also describes a mould for wind turbine blades having a vacuum flow topology prepared by such a method. |
