Carbon nanotubes disappoint EADS Composites Atlantic

Abstract:
Carbon nanotube (CNT) use in composite structures is not delivering the expected advantages after a year of development, according to EADS company Composites Atlantic.

The incorporation of CNT in a composite's matrix had been expected to deliver increases in mechanical strength and damage tolerance.

However, Composites Atlantic's C$30,000 ($29,000) of research into the use of CNT, supplied for free by its manufacturer, has been inconclusive.

"We wanted to see how CNT would benefit the manufacturing process and wanted to validate those benefits," says Composites Atlantic vice-president engineering Claude Baril.

The company is in discussions with the CNT supplier to determine why the nanotubes are not enhancing the performance of composite materials.
