How is 3Dr similar to 3DL?
Both 3Dr and 3DL are 3-dimensionally thermo-molded sails. Materials used
and 3-dimensional shaping are the same and lamination for both uses heat,
vacuum pressure and proprietary adhesives.
How is 3Dr different from 3DL?
1. 3Dr yarn layouts are optimized for application
onto a moving surface rather than a stationary one.
2.
Shaping method is different. The 3Dr drum mold surface is
shaped using the principal of Gaussian curvature. 3D
curvature is created in two directions. The circular form
of the drum (A) forms
one axis. The controlled curvature across the drum surface
(B) is the other axis. 3D curvature of sail = A x B.
What fiber is used
in a 3Dr sail?
3Dr is currently made using aramid fiber.
Is 3Dr delivery faster than 3DL?
Yes. Delivery is faster for two reasons:
1) The remarkable efficiency
and output of 3Dr system can produce more sails in less time and,
2) there is a faster curing time for
the 3Dr laminate.
Is pricing lower for 3Dr sails?
Yes. Price for a 3Dr sail is lower because of higher efficiencies of
3Dr system where all steps — molding, yarn application and vacuum/heat
bonding — are performed simultaneously, rather than in consecutive
steps.
Are there any size limits to 3Dr sails?
Yes. 3Dr sail limits depend on a number of factors, but the current
maximum thread density is approx. 15,000 dpi and the current maximum
foot dimension
is approx. 6.7 meters. |
