Tooling and production materials from Huntsman Advanced Materials have been selected to construct a new One Design carbon racing yacht in a project which sees Huntsman supporting each stage of the project; from design through to the finishing techniques in production.

 

The ‘CODE8’ is a light displacement, high performance racing yacht.  Designed by America’s Cup yacht designer Andrej Justin and professionally crafted by Carbon Innovation Ltd, the ‘CODE8’ is set to compete in top level local and international regattas.

 

Carbon Innovation decided to use Huntsman’s production materials after consultations with Farix Ltd, Huntsman’s distributor in Hungary.  The materials were chosen for their toughness, high quality surface finish and dimensional accuracy.  Also, in the case of parts production, they were specifically selected for their heat and chemical resistance properties.

 

CAD data was initially used to produce a plug of the yacht from a PSFoam substructure and (RenPaste® SV36 / Ren® HV 36) modelling paste.  The parts were then CNC machine milled to create a master model for fast extrusion, exhibiting both low shrinkage and a smooth surface finish.

 

A high performance gel coat (Resin XD4615 / Ren® HY 5159) was then applied to the master model and a backing layer was built up (using Renlam® CY219/XB5173 in combination with glass fiber) to form the mould for the hull, deck and all other parts.

 

The hull and deck have been produced from the mould using a hot curing system for vacuum infusion (GL certified, Araldite® LY 1564 / Aradur® 2954) and bonded together with an epoxy adhesive (GL certified, Araldite® 2015) which forms durable, elastomeric joints that are water tight and weather resistant. 

 

Combining low viscosity with a long pot life at elevated temperatures, the hot curing system offers excellent mechanical, dynamic and thermal properties.  Optimised to provide high Tg, this high temperature resistant system is also suitable for the manufacture of boats finished in dark colours, such as black or dark blue.

 

For other components, including the mast and rudder, an Araldite® pre-preg system (Araldite® LY 1556 / Aradur® 1573 / Accelerator 1571 / Hardener XB 3403) was selected and used in combination with Carbon Innovation’s self-developed pre-preg machine.  This system has an easy B-staging and GL certification and can also be used for wet lay-up; filament winding and resin transfer moulding.

 

“Using Huntsman’s products and systems throughout the project has optimised our management time and provided a central expert source of technical know-how and product supply,” said Tamas Simon, Managing Director at Carbon Innovation.

“On a practical level we are realising cost benefits and are on target to meet our time to market objectives, with minimal waste and downtime.  The quality of parts has matched the ambition of our design at every stage.”

 

The ‘CODE8’ has been built to the highest standards, utilising state-of-the-art construction materials and production technologies comparable with that used in America’s Cup yacht construction and fit out.  Progress through the design, development and production stages was rapid, with the first ‘CODE8’ yacht having taken 4 months to complete. 

 

The boat will first take to the water to compete in the Keszhely-Kenese, a short handed solo race, on 20th August.  In September, it will compete in both the Centomiglia at Lake Garda on 10th and the TBS cup at Lake Balaton on 23rd.  Following this, on 9th October the ‘CODE8’ is scheduled to compete in the Barcolana.
