l

nstalled in the port of
Valencia (Spain), the
corrosion-resistant lighthouse is 4.5m in diameter with a regular octagon
shape, a bonded structure
and a self-illumination system (using PV solar panels).
The installation process was
quick and easy; only 6 hours
thanks to the structure's low
weight (20 metric tons). The

Several technical challenges
had to be overcome to complete this project within the
given time frame.
First, the project required
the pultrusion of 20mmthick CFRP tubes meeting
the strength, chemical and
architectural requirements.
The pultrusion of these
tubes involved the uniform
impregnation of more than
5000 carbon fibre tows and
10 layers of heavy-gram-

mage pentaxial carbon fibre
fabric in order to achieve a
void content under 3% and a
24h water absorption lower
than 0.5%. The continuous
and uniform impregnation
of these huge quantities of
reinforcement using common systems such as open
bath or resin injection alone
resulted in frequent production breakdowns owing to
(i) fuzz generation and subsequent viscosity rise of the
resin mix in the case of open
bath, and (ii) poor impregnation of the tows due to
insufficient permeability because of a high fibre packing
density within the resin injection chamber. Therefore,
the research team developed
an innovative fibre impreg-

nation system combining
the benefits of both open
bath and resin injection to
overcome these difficulties.
Saertex (Germany) was in
charge of developing the
pentaxial carbon fibre fabric, while DOW chemical
supplied the low-viscosity,
fast-curing pultrusion resin.
The second challenge was to
design and develop suitable
bracing elements. In order
to transfer the moment from
the vertical CFRP tubes to
the horizontal GFRP tubes,
low-weight,
low-maintenance bracing elements with
a smooth surface and high
chemical and mechanical resistance had to be designed
and manufactured. A new
