Sensor measures sub-surface flaws
Abstract
It is notoriously difficult to detect and measure faults below the surface of composite materials, such as carbon-fibre reinforced flaps for aircraft, radial tyres for lorries, and even sports shoes. Now a prototype laser-assisted inspection system can find and map hidden defects in vehicle tyres, dashboards and rubber-metal objects such as valves for tubeless tyres. The technology can cut the cost of quality inspections by 90 %.
