Godiva2 is a human powered submarine that was 3D-printed and designed with an innovative bio-based hull infused with 3M Glass Bubbles to ensure stability and the best underwater buoyancy.

3M Glass Bubbles are high strength, low density hollow glass microspheres and are also used across the manufacturing industry in a range of applications from improving the performance of paints and coatings to reducing the weight and improving the dimensional stability of rubber and plastic components.

The WarwickSub team was determined to create the most innovative, refined and high performing submarine in the history of the competition, so got in touch with advanced materials experts from 3M.

Said marketing executive for 3M’s Advanced Materials Division, Kirstie Heneghan: “We supplied the team with 3M Glass Bubbles which they mixed with resin to bind fibre glass and flax to create the composite structure for the hull. We also introduced the team to a range of 3M structural adhesive, abrasive and surface cleaning products.”

Godiva2 was officially launched to an audience of sponsors, academics and other interested parties at a ceremony held on the Warwick campus in May.

Said WarwickSub’s project leader Josh Dobson: “This year we were able to innovate further and faster with the help of 3M products and we are looking forward to putting Godiva2 to the test in the water.”

Universities from all over the world will compete in the submarine races that will be held in Portsmouth from 6-15 July, with one event open to the public on 9 July at Hilsea Lido and Blue Lagoon. You can find out more about the WarwickSub project in this YouTube video.
