What this video covers

Timo and Jo are repairing a 9-metre carbon fibre boom for their Open 60 sailboat, NV.0:07 To rejoin the two sections, they are fabricating a custom carbon fibre sleeve using a vacuum-bagging lamination process.0:11 The team applies multiple layers of 1,000 grams per metre squared carbon fibre, alternating between unidirectional and bidirectional strips, wetted with epoxy.8:20 After the first two laminations, the sleeve reached a thickness of 2 millimetres.4:19 When the vacuum process compressed the sleeve ends, Timo corrected the profile using foam strips and filler.7:25 During the third lamination, the vacuum bag imploded due to excessive space between the internal pipe and the sleeve.15:40 The crew resolved this by removing the pipe and wrapping the entire assembly in an additional vacuum bag to ensure a proper seal.15:40 The repair requires high structural integrity to withstand the extreme loads typical of an Open 60 rig.0:28
