- Abstract
A non-contacting laser correlation sensor is used to determine the strain of different ceramic (alumina, silicon carbide) and carbon fibres in a single fibre tension test. The diameter of these fibres varies from 15 to only 5 ?m, which makes the application of conventional strain sensors impossible. The advantage of the non-contacting method is that the strain is directly measured and end-effects from the gripping system need not to be considered. Results for different ceramic and carbon fibres with linear and non-linear stress-strain curves are presented as an example. Π2003 Elsevier Ltd. All rights reserved.
