FIRST AGAIN. 15 years ago Jean
Louis Colmas started to develop wood sandwich boards in New Caledonia.
Today the rest of the industry has adopted his development in their manufacturing
of quality sandwich boards by using wood as reinforcement in high stress
We however use wood in the whole deck and bottom
area in our WOOD tech boards to increase strength and rigidity
in all areas . The selected 0.6 mm Australian Pine absorbs minimal resin
which leads to an especially light laminate.
has over the last 3 years been testing the Dyneema
reinforced wood technology in our boards. The results are so remarkable
that , that we decided to lead the windsurfing world into a new dimension
of construction quality by implementing this innovation
as reinforcement in our WOOD technology .
also used as rail reinforcement in our new D-RAM
( Dyneema Reinforced Airex Model) technology.
IS ONE OF THE WORLDS STRONGETS FIBERS?
DYNEEMA is a high performance polyethylene (HPPE) fibre, was developed
by the Dutch Chemical Group DSM, and is manufactured by DSM High Performance
Fibers. It is produced by a unique gel spinning process where molecules
are dis-entangled to enable parallel orientation, giving the fibers its
unique properties. Dyneema's strenght and low density makes it one of
the world's strongest commercially available fibers.
The strength and relative high elongation to break gives the fiber the
ability to absorb a great amount of energy. The Sonic velocity , over
10 km/sec , allows extremely high distribution of energy. DYNEEMA
IS USED BY THE US DEPARTMENT OF DEFENSE AS ABSORPTION OF BALLISTIC ENERGY
( bullet proof jackets), and by Starboard to increase the lamination strength
of our sandwich construction boards.
Reinforced WOOD Sandwich Construction.
DSM has in co-operation with several industrial partners, performed a
special research on the combination of wood and Dyneema, and concluded
that by using one single reinforcement of Dyneema under wood, a significant
improvement of the resistance against high energy impact is reached. We
have taken it one step further by developing a combined sandwich construction
of 3mm 100kg density Airex, light glass fiber, Dyneema rail reinforcements
and 0.6 mm Australian Pine wood, bringing forward the technology of the
Dyneema Reinforced Airex Model,
is a full body Airex Sandwich construction with rails and impact areas
reinforced by Dyneema. We also have wood reinforcements under the standing
area and in the nose section where the mast may hit.
