Recycled materials for the Britannia’s hull cradle



In the build-up to the 36th America’s Cup, ELG Carbon Fibre has processed over 1.2 tons of INEOS Team UK’s waste materials and used it to produce two cradles for the new racing boat ‘Britannia’.

Moulds for the hull regions of the team’s test boats have also been manufactured using the same technology.

INEOS Team UK’s waste comprised of pre-impregnated and cured parts from its current campaign, which ELG has subsequently reprocessed into thermoset and thermoplastic compounds and nonwoven mats.

Britannia was officially launched last month at the team’s UK’s headquarters in Portsmouth. The 75-foot foiling monohull is the first of its size and represents an entirely new breed of race boat. A structure of this proportion requires a strong and stable cradle to support the boat in transit. 



ELG’s nonwoven carbon fibre mats were used to produce the curved cradles the hull sits upon. The company’s technical service engineers were on hand to provide guidance about the specific processing requirements for these materials. Vacuum infusion was selected as the most economic method for manufacturing these parts, although ELG materials can also be used in prepreg and liquid compression moulding processes. ELG’s products were also incorporated into the hull mould, which again was made using a vacuum infusion process.

 “ELG’s technology was ideal for the cradles application,” said Alan Boot, Naval Architect at INEOS Team UK. “The recycled materials are easy to handle, perform well and fitted straight into our production processes.  As an America’s Cup Team, we hope to lead the way showing other manufacturers you can avoid putting materials in landfill, close the loop and reuse the fibres with stunning results. This is a game changing approach to marine manufacturing that we are delighted to be part of.”
