Hexcel’s HexPly XF Surface Technology Revolutionizes the Blade Surface Finishing Process

January 04 (2021

Hexcel apprises of its latest HexPly XF surface technology that significantly reduces shell manufacturing time within the wind blade surface finishing process. HexPly XF increases overall blade manufacturing efficiency by reducing time in the mold by up to two hours and by banishing surface defects that require rework before painting.

HexPly XF surface technology satisfies the most challenging surface quality requirements by introducing a new material format as the surface finishing layer, eliminating the need for a traditional in-mold gel coating process. HexPly XF for infused rotor blades, is a lightweight non-woven semi-preg construction, comprising an epoxy resin matrix, that co-cures with standard epoxy infusion systems. The product has a successful track record in prepreg blades and has now been adapted for infusion processes.

Easy to handle and supplied in a ready to use roll form, 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.

HexPly XF material is less than half the weight of a typical gel coat per square meter, reducing the overall weight of the blade. 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.

The material has a shelf life of six weeks at ambient temperature, which also minimizes cold storage requirements and helps to reduce scrap.
