Surface technology for wind turbine blade surface finishing
HexPly XF can be quickly applied by hand or with semi-automated layup equipment. It features one self-adhesive, surface finishing side - indicated by a removable protective foil. This side of the prepreg is placed against a release agent treated mold surface. Once the material has been positioned, the lay-up of the blade shell structure can start immediately, and the laminate can be infused. After curing, the blade is de-molded with minimal preparation needed before painting.
The material is less than half the weight of a typical gel coat per m², reducing the overall weight of the blade. Additionally, the consistent areal weight and thickness of the prepreg film provide a completely uniform surface coating, ensuring blade weight distribution and balance are maintained.
With no need to handle or mix liquid chemicals as in the gel coat process, HexPly XF also improves the health and safety working conditions on the shop floor.
