Hexcel’s HexPly® XF surface technology revolutionizes the blade surface finishing process

Hexcel is pleased to announce 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.

As the surge in wind energy continues, wind turbine manufacturers are under increasing pressure to reduce costs, increase quality, and optimize productivity. Hexcel’s HexPly XF surface technology has been formulated to address the limitations of current blade shell surfacing techniques whereby pinholes and other surface defects have to be repaired by hand to achieve the perfectly smooth surface required for 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. 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 the manufacturer benefitting from a pinhole-free surface that needs minimal preparation before painting.

HexPly XF material is less than half the weight of a typical gel coat per square meter, 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, which is critical as rotor diameters continue to increase. 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.

Novel flame-retardant and recyclable fiber-reinforced composite

Airplanes and passenger trains must meet strict safety requirements, including fire safety standards. This calls for materials that are flame-retardant, lightweight, robust, and scalable. Empa researchers, in collaboration with their industry partner Elantas, have now succeeded for the first time in making such a material – a composite – fully recyclable.

WHILL selects Teijin’s tough, lightweight Carbon Fiber Composite for new last-mile mobility

Teijin Limited announced today that WHILL Inc., a global leader in inclusive mobility technology, has selected Sereebo® P CFP series, a carbon fiber-reinforced thermoplastic (CFRTP) material, for key structural components of the upcoming WHILL Model C Lite. Sereebo® P CFP series provides high strength, light weight, design flexibility and system cost advantages to the Model C Lite, which is a battery powered, single-seat, last-mile device. This new model combines maneuverability with light weight and one-handed folding to ensure ease of handling and operation.

Fewer pores, greater impact tolerance: Peter Dornier Foundation Prize 2026 honours material research on fibre-reinforced composite components for aerospace industry

Microscopically small pores that form during manufacture, or barely visible impact damage, can severely impair the load-bearing capacity and service life of fibre-reinforced composite components. Two young researchers have presented groundbreaking work in this field and will both be awarded the 2026 Peter Dornier Foundation Prize: Dr.-Ing. Benedikt Neitzel from the Technical University of Ilmenau for his doctoral thesis on pore minimisation in the RTM process, and Johanna Buschmann, M.Sc., for her master’s thesis, completed at the German Aerospace Centre, on the improved impact tolerance of 3D fabrics compared to 2D laminates.
