Tests
carried
out
at
the
German
industrial
group’s
wind
power
competence
center
in
Otterup,
Denmark,
suggest
the
freer-flowing
resins
–
liquids
drawn
through
laminates
of
fibre-glass
in
a
mould
to
form
composite
blades
–
spread
more
evenly,
more
quickly,
and
harden
faster
than
current
versions,
potentially
cutting
blade
manufacture
cycle
time
from
16-24
hours
down
to
seven
to
eight
hours.
The
finished
rotor
blades
“are
sturdier,
longer-lasting
and
more
lightweight
than
those
produced
with
the
epoxy
resins
and
unsaturated
polyesters
used
previously”,
claims
the
company.
“We
are
working
to
cut
the
cycle

still
further,”
