times for the former and high
Tg for the latter.
Benteler-SGL and Henkel
have, for example, developed
new leaf springs based on a
polyurethane matrix using
an RTM process. While the
benefits of composites with
these types of applications
are now beyond doubt, the
partners believe that they have
found a still more advantageous solution for this type of
application, mainly using, for
now, prepregs.
Prepregs still have plenty to
offer, and can now reconcile
two properties that appear in
principle to be incompatible:
fast curing and long shelf life,
as demonstrated by Hexcel.

automation potential for mass
production. It is clearly the
automotive industry that is
the target sector of choice. By
focusing only on the matrix
part, engineers on the lookout
for solutions will have to sort
through the solutions on offer,
since the marketing experts of
the various companies highlight time scales that are not
necessarily like-for-like (cure
time, cycle time, part-to-parttime). Whatever the case, the
two minutes or less spent in
the mould for injection of the
resin are a target attained by a
number of competitors.
... mainly with epoxy...
Among the latest examples to
date, we mainly find the big
players in epoxy resin: BASF,
Cytec, Dow, DSM, Henkel,
Huntsman, Momentive and
Swancor. Judging from the last
two sessions of JEC Europe,
these companies place enormous faith in the automotive
market. The indicators are
indeed positive for composites
on this market, a market that
should really blossom with the
introduction of new envi-

ronmental standards as from
2020-2021, in Europe, the
United States and also China.
There should naturally be a
progressive ramp-up between
now and then in the form of a
classic learning curve.
... but other solutions
exist
Several manufactures are
banking on polyurethane, such
as Henkel, or cyanate ester,
such as Lonza, to target the
same market. These formulations also have their advantages, such as very short cycle
There are many sectors
that could benefit from the
targeted developments made
for the automotive sector. Not
least the aerospace industry,
which for now makes do with
"long" curing times in the
order of 30 minutes for RTM.
Yet future programmes, that
will ultimately supersede the
Airbus A320 and Boeing 737,
will require far higher production rates. Alternatives will
therefore need to be found. n
