‘Sharkskin’ makes planes faster, smoother, cheaper

A sharkskin-inspired coating on planes will save thousands of dollars per flight and slash carbon emissions, says Aussie start-up, MicroTau.

The Clean Energy Finance Corporation (CEFC) today announces a $5.6 million investment in MicroTau’s ‘sharkskin’ technology developed with the help of the Australian National Fabrication Facility (ANFF).

Sharks famously swim smoothly and quietly, helped by their unique skin with thousands of overlapping layers of tiny ‘scales’ or denticles to reduce their drag in the water.

Mimicking this structure on airplanes reduces turbulence, increases flying speed, and cuts fuel emissions and cost. Unfortunately, it is excruciatingly difficult to replicate the microscopic grooves and bumps with traditional manufacturing.

MicroTau have solved this puzzle using specialist laser manufacturing technology to rapidly produce the shark skin pattern in a light-curable material onto large, self-adhesive patches. Today’s funding announcement will allow them to scale-up manufacturing and grow their team of scientists, engineers, and business development specialists.
