Aquabatten Leech Uniform Glass Batten
Aquabatten Leech Uniform Glass Batten – A laminated batten using a multiple pre-preg scrim layup with the taper built within the layup, ensuring that the outer surfaces are complete from end to end – no exposed glass fibre.
- Unique layering process reduces the risk of inter-laminar bond failure
- No filaments cut in tapering process – unique laminate construction encapsulated in a multi layer outer casing
- Minimised batten failure – reduces replacement costs
- Construction reduces stress – maximum stress is dissipated along the batten
In line with market leading sail design software which utilises FEA (Flexible Element Analysis), these systems express batten specifications in terms of an EI number. As a result, Bainbridge has now engineered aquabatten to cover a balanced range of EI numbers, giving the widest possible range to maximise application of aquabatten products in modern sail designs.
By manufacturing the product in an advanced bi-directional scrim lay-up, aquabatten uses up to 56 laminations which are totally encapsulated; therefore the inherent strength of the construction is not ground away. This is the case with most other tapered battens. This ensures greater structural integrity, strength and also durability.
- Handles torque stress caused by twist, where uni-directional battens fail
- Increased durability and strength when sail is stored or covered
- Epoxy resin composition gives a stronger, hydrophobic batten which keeps the batten at design weight while eliminating loss of strength in the resin
- Battens carefully calculated to a specific EI number (stiffness) for easy product selection
Developed to offer the most comprehensive range of widths, lengths as well as types. Designed to suit the very latest sail designs while continuing to offer the very best performance.
Aquabatten Leech Uniform Glass Batten Features:
- Increased durability due to hydrophobic epoxy resin systems ensuring the designed weight and strength
- pre-preg scrim is bi-directional to prevent the batten from twisting from torque
- EI numbers for all battens give the specific stiffness which corresponds to Sail Design program FEA output
- Range covers dinghies all the way to 60 foot yachts
- Other widths are available to special order with no minimum order quantity
Definition of EI
EI is an expression of the ‘Flexural Rigidity’ of a bar – flexural rigidity is simply defined as the resistance offered by a structure while undergoing bending.
Understanding of EI
E = the stiffness of the material (Young’s Modulus).
I = the stiffness of the shape (form) itself.
Therefore EI is the combination of the material and the shape. In combining the two together (EI) it delivers a ‘common comparator’ which allows you to technically specify the correct batten for that particular part of the sail construction.
Therefore, the higher the EI, the ‘stiffer’ the batten will be.
By using EI, a sail maker has the flexibility of reducing the width of a batten by increasing the thickness, this enables lighter battens to be specified in the sail design – as a result you have a lower weight sail delivering improved performance.
