Flax Balsa

Flax Balsa is an innovative technology using natural uni-directional flax fibres to add stiffness instead of carbon fibres, combined with an end-grain balsa bottom sandwich and a recyclable PET foam deck sandwich.

A high performance, full sandwich construction that avoids the use of PVC.

WHY BALSA?

HONEYCOMB PROPERTIES

By turning the balsa grains vertically within the sandwich structure, Starboard’s innovative end-grain sandwich connects the top and bottom faces with millions of vertical, honeycomb-like pillars.

The result is significantly higher mechanical properties than conventional petroleum-based PVC:

3x shear modulus | 3x tensile strength | 20x tensile modulus | 2.75x compressive strength

RECYCLABLE P.E.T. FOAM SANDWICH

T10

Starboard introduces T10 PET foam sandwich: an innovative next-generation sandwich material developed by Airex® as a less toxic replacement for PVC.

This new generation of polyethylene terephthalate (PET) technology has much improved mechanical properties, making them a perfect new alternative to PVC foam without the footprint.

UNI-DIRECTIONAL FLAX FIBRES

NATURE'S WONDER MATERIAL

Finely woven uni-directional Flax fibres, like carbon fibres, add exceptional stiffness and crispness to a board. Our lab measurements have shown Flax fibres to even exceed carbon in stiffness and tensile strength.

Our Flax Balsa boards use flax fibres in the back half of the board, from the back footstrap to the mast track.

FLEX OPTIMIZATION

UNI-DIRECTIONAL CARBON RAIL BANDS

Along the rails, we’ve added extra-light uni-directional carbon stripes to further stiffen the board between the back foot and the mast track.

SICOMIN BIO RESIN

GREENPOXY 33

We use GP33 plant-based bio resin from Sicomin which has half the carbon footprint of conventional, petroleum-based epoxy resin while maintaining a clear, high performance laminate with excellent U.V. resistance.

EPS CORE

15.5 g/cm³ Density

Waterproof, shear resistant, fused and moulded individually to fit each and every Starboard mould to minimize waste.
