The Halo's composite ring was made by Innovation Composites using Gurit materials.
The Halo's composite ring was made by Innovation Composites using Gurit materials.

‘Halo’ is a giant yellow ring, measuring 12 m in diameter, attached to a 6 m long silver arm, which is atop a 13 m tall silver pole. The ring tilts and turns in response to the wind. The weight of the ring and arm balances on a tiny ceramic bearing, the size of a small glass marble.

After the initial structural design concept had been developed, Gurit engineers utilised advanced finite element analysis to run a series of design optimisations, which investigated optimum laminate placement to achieve the desired results.

The composite ring was made by Australian company Innovation Composites using Gurit double bias carbon with E-glass cloth and carbon tapes, hand laminated with Ampreg 22 epoxy resin. The plug and mould for the part was made by Mouldcam, Australia, using Gurit T-Paste 70-2.

The supporting arm was manufactured by Innovation Composites using Gurit SE 84 LV prepreg.

This project  will be open to the public from December.
