TTT The Team Composite AG (Stade, Lower Saxony, Germany) is a highly skilled team of engineers who have developed innovative commercial vehicle solutions using carbon fiber reinforced plastics (CFRP). Two of its developments are already on the road – a tipper semi-trailer and mega curtain-sider trailer. Both of these developments have been well received and have won several design awards for technical innovation.
Following on from this success TTT has
developed a reefer trailer that makes extensive
use of carbon fiber sandwich composites
based on Diab’s Divinycell H grade
polymer cores. A prototype has already been
built by Hatecke GmbH who is perhaps
better known as one of the world’s leading
producers of lifeboats and high speed rescue
craft. Hatecke will also be fabricating
the production versions of the trailer at its
main production facility that is located in
Drochtersen, Lower Saxony.
Many government bodies and freight organizations are convinced that this new trailer has the capability to make a substantial contribution to the reduction in the CO2 footprint of commercial vehicles. The development has already been recognized with TTT winning a JEC Innovation Award.
Aldi Sued, the pan-European supermarket chain, will be taking delivery of the first production versions of the trailer.
By choosing to produce the trailer chassis
and deck in carbon fiber sandwich
composites using infusion
molding TTT has been able
to substantially reduce the
weight of the trailer while
still meeting the required
levels of strength and stiffness.
With TTT’s optimized design
the trailer is approximately 3,500 kg (3.85 US
tons) lighter than an equivalent trailer made
from steel. Also the design freedom provided
by sandwich composites has allowed TTT to
produce a more aerodynamic shape.
These two factors mean that the diesel
consumption is cut by up to 25%, vehicle stability
has been improved and life cycle costs
have been reduced. Also total cargo volume
has been increased by using a new kind of insulation
that is embedded in a CFRP frame
work and the cover sheets in the reefer body.
Vehicle stability has also been improved.
Other design features of the new trailer include
integrated under run protection and
under deck storage for up to 36 Euro pallets.
