CVD diamond-coated fibres

Diamond-coated fibres have been fabricated using hot filament chemical vapour deposition (CVD) and tested for mechanical stiffness. The fibres coated include small (< 20 μm diameter) commercially available samples such as Nicalon, Tyranno, Nextel, Altex and Hi-Nicalon, as well as thicker (100–150...

Description
Summary:Diamond-coated fibres have been fabricated using hot filament chemical vapour deposition (CVD) and tested for mechanical stiffness. The fibres coated include small (< 20 μm diameter) commercially available samples such as Nicalon, Tyranno, Nextel, Altex and Hi-Nicalon, as well as thicker (100–150 μm diameter) SiC-based fibres produced by Textron and B.P. Mechanical bend tests show that the fibres were significantly stiffened by the addition of a CVD diamond layer of a few micrometres thickness, giving a Young's modulus value close to that for natural diamond.
