Sandwich composites are increasingly being used for a wide range of train applications as train operators look to increase performance, cut weight, reduce noise and improve comfort. By using Divinycell P, train builders are now able to take advantage of the benefits of sandwich composites for interior components while meeting the latest FST (fire, smoke and toxicity) requirements.
The new DMU (diesel multiple unit) train
from Croatian train builder TŽV Gredelj
makes extensive use of Divinycell P with thin
aluminum skins for the train floors and
other interior panels. Apart from reducing
weight without compromising strength,
Divinycell P was chosen for this application to eliminate internal structural noise and thereby provide passengers with a much quieter travelling experience. In addition to supplying core materials, Diab also provided TZV Gredelj with engineering support.
TŽV Gredelj’s new DMU has been
developed for regional traffic duties. It is a
three-part train set comprised of two end
motor modules with driver’s cabs and one
middle motor module without a driver’s cab.
TZV Gredelj has been producing train
rolling stock for more than 117 years. Its
main production facility in Zagreb covers a
total area of 350,000 m2 (3,768,000 ft2), of
which 80,000 m2 (861,113 ft2) is covered.
As well as being the principle supplier
of train sets to the Croatian railway authorities,
over 40% of TZV Gredelj production
is exported. Its rolling stock is in operation
around the world — everywhere from
Argentina to Saudi Arabia.
