Abstract

A method for fabricating leading edge (LE) erosion protections shields for wind blades is proposed. The method includes bonding an erosion protective layer to the LE using a heat activated film. The bonding film has a low tack application temperature, allowing positioning of the protective layer to the blade surface. Positioning of the protective layer on the blade surface is followed by consolidation of the bonding film and the protective layer on the blade surface with the help of external pressure using, for example, a vacuum bag. Air trapped between the blade surface and the bonding film and between the bonding film and the protective layer is removed by the vacuum. Use of bonding film different and independent of the protective layer allows use of protective layer material having desired characteristics for protection against harsh environmental conditions.
