Adhesives keep innovative boat afloat

The Chantier Naval de Larros team specified the use of Araldite 2022 and Araldite 2031 adhesives to bond the boat's bulkhead to its hull, which was machined from carbon-nomex sandwich panels.
Araldite 2031 (a black epoxy adhesive) and Araldite 2022 have played a vital role in the construction of Safran Open 60 - a pioneering new monohull racing boat that competed in the Vendee Globe round the world solo race, March 2008.
Safran Open 60 is a 60 foot long, ergonomic, lightweight vessel.
Designed to weigh less and be more manoeuvrable than other boats in its class, the Safran Open 60 was built by the Safran Group of Companies at the Chantier Naval de Larros shipyards (CNL) in France.
The project - which took five months to complete and involved 4600 hours of R and D and engineering time - is the first maritime initiative of its kind where a sponsoring company has played an active role in development.
During construction of the vessel, six companies from the Safran group were involved in the project working alongside Van Peteghem-Lauriot Prevost and Guillaume Verdier.
In order to meet racing requirements, the Chantier Naval de Larros team specified the use of Araldite 2022 and Araldite 2031 adhesives to bond the boat's bulkhead to its hull, which was machined from carbon-nomex sandwich panels.
Araldite 2031 was also employed to attach key pieces of ironmongery during the build and to build the ballast tank entrance.
Commenting, Thierry Eluere, Managing Director of the CNL shipyard and an internationally renowned boat builder said: "The team that worked to create the Safran Open 60 in our shipyard are all perfectionists".
"Transferring expertise and knowledge originally gained in the aerospace industry, the team was chosen because of their attention to detail and the stringent performance requirements they demand of all of their design materials".
"These characteristics are mirrored in the CNL mantra and ensure we have the skills and discipline required to build world class racing boats".
"When it came to selecting the best range of adhesives to use in the construction of this responsive racing machine, the decision for the whole team was very simple".
"We chose Araldite 2000 Plus because of the breadth of the range and the exceptional track record of its products".
"Araldite 2031 and 2022 did not disappoint".
"In fact our technicians said they had never come across a structural adhesive quite like Araldite 2031 before".
"Once the adhesives had been applied, we checked the quality of the bonds created and testing their load bearing capacity".
"This was done under rigorous conditions to guarantee that the product could withstand the forces experienced at sea under real racing conditions".
"Again, we were more than satisfied".
