Beschreibung
Zusammenfassung:	A method for manufacturing a composite is provided herein, including laying at least one reinforcement layer onto the inner surface of a mould, positioning a degradable membrane onto the outermost reinforcement layer of the at least one reinforcement layer, applying suction between the inner surface of the mould and the degradable membrane to press the at least one reinforcement layer towards the inner surface of the mould, covering the degradable membrane with at least one vacuum film, generating a vacuum in the region between the vacuum film and the mould, injecting resin into this region by means of vacuum, and letting cure the resin, initiating a degradation of the degradable membrane by provoking a physical or chemical change of the membrane material after having generated a vacuum in the region between the vacuum film and the mould and before the resin has cured completely.
