Abstract
The present invention relates to a covering for rotor blades comprising a fabric and a protective top layer, the covering having a weight of up to 800 g/m2, the covering having an elongation at break in both a warp and a weft direction of at least 20%, wherein the elongation at break is determined according to ISO 13934-1:2013, wherein the protective top layer is a film, and wherein the protective top layer is laminated to the fabric. The invention also relates to a use of the covering for covering rotor blades of a wind turbine.

Use of a covering for covering wind turbine rotor blades, wherein the covering for rotor blades comprises a fabric and a protective top layer, wherein:
- the covering has a weight of at most 800 g/m2,
- that the covering has an elongation at break in both a warp direction and a weft direction of at least 20%, wherein the elongation at break is determined according to ISO 13934-1:2013,
- that the protective top layer is a film, and
- that the protective top layer is laminated to the fabric.
A rotor blade, comprising:
- a covering, consisting of:
- a fabric comprising a polymer,
- a polymeric protective top layer, which is a film and is laminated to the fabric, and
- an adhesive layer between the fabric and the protective top layer,
- wherein:
- the covering has a weight of at most 800 g/m2,
- the covering has an elongation at break in both a warp direction and a weft direction of at least 20%, wherein the elongation at break is determined according to ISO 13934-1:2013.
