Abstract
A method for preparing a more reliable connection between two members (2, 4) is provided. The method involves the use of a gas-removal layer (6), which allows for gas transport in a number of overall directions in a plane of the gas-removal layer. The gas-removal layer comprises a resin (12) and during consolidation the gas-removal layer is deformed to form a collection substantially free from entrapped gas voids. Furthermore, a gas-removal layer is provided as well as a mould for casting of gas-removal layers and a method for preparing such a mould. The method and the gas-removal layer provided are particularly useful for manufacturing of wind turbine blades and spars for such blades.
