Space technology goes against the grain

The engineers, all former employees of the aerospace division of Chum Group Oy, believe a composite fuselage made from 40 per cent redwood fibres will provide the spacecraft with three desirable qualities required for travel beyond Earth’s orbit.

‘It sounds crazy but this has been proven our lab tests,’ said Robert Wood, chairman of Suffolk-based Composite Space Exploration. ’One, it’s light so will use less fuel. Two, its strong, and it’ll bloody well need to be to get into space. Three, wood is renewable so that ticks all the ‘sustainability’ boxes.’

Wood explained to The Engineer that fibres from the redwood tree can be extracted in an environmentally-friendly way and then recombined with what he described as ‘proprietary materials’ to make a composite fuselage that tolerates exceptionally high temperatures and pressure.

The company’s laminating process, which is subject to a patent application, is also key to the mission, as it will help form an ablative skin for re-entry.
