New surfacing technology enabling
high-quality paint-ready surfaces
Hexcel recently released its latest HexPly®
XF surface technology that
signifi cantly reduces shell manufacturing time within the wind blade
surface fi nishing process. According to the company, HexPly XF increases
overall blade manufacturing effi ciency as it reduces time in the mould
by up to two hours and eliminates surface defects that require rework
before painting. Other markets are also targeted for this new product.
prepreg blades and has now been adapted for
infusion processes (Figure 1).
T
he HexPly XF surface technology was
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. It introduces a new material format
as the surface fi nishing layer, eliminating the
need for a traditional in-mould gelcoating
process.
HexPly XF for infused rotor blades is a lightweight
non-woven semi-preg construction
comprising an epoxy resin matrix that cocures
with standard epoxy infusion systems.

JEC Composites Magazine: Could you give
us a brief introduction to the HexPly®
surfacing
technology? What type of product is
it and how does it benefi t the composite

Smooth surface, smooth manufacturing
Easy to handle and supplied in a ready-touse
roll form, HexPly XF can be quickly
applied by hand or with semi-automated
layup equipment. Once the material has
been positioned, the lay-up of the blade
shell structure can start immediately, and
the laminate can be infused. Aft er curing,
the blade is de-moulded, providing a
pinhole-free surface that needs minimal
preparation before painting. Th e material is
less than half the weight of a typical gelcoat
per square metre, reducing the overall weight
of the blade. Additionally, the consistent
areal weight and thickness of the prepreg
Achim Fischereder: In composite
material terms, HexPly® XF is a lightweight,
non-woven, semi-preg, epoxy resin material
that replaces traditional in-mould gelcoats
used in the manufacture of composite components
such as wind turbine blades. For
the end-customer, it is an innovative surface
technology that removes the need for gelcoat
and the time-consuming refi nishing work
typically required to obtain a paint-ready
surface. In short, we are pleased to report that
HexPly XF reduces costs and produces lighter,
more consistent parts with shorter cycle
times and a cleaner working environment.

fi lm 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 gelcoat process, HexPly XF also
improves the health and safety conditions or
workers on the shop fl oor.
Th e material has a shelf life of six weeks at
ambient temperature, which also minimizes
cold
storage requirements and helps
to
reduce scrap.
In the interview below, Achim Fischereder,
Hexcel Industrial Marketing Director, says
more about this new product.

Several challenges exist in the composites
world at the moment, from raw material
supply chains through to end-customer demand.
How have these challenges impacted
Hexcel's product development strategy and
which markets are you targeting with HexPly
XF?
A.F.: Th is is absolutely right. Th ere have
certainly been some challenges regarding
raw material supply chains in the glass fi -
bre and chemicals markets during the past
months, although we have worked extremely
hard to minimize the impact on deliveries
to our customers. Coupled with this tight
