摘要：
The bending method, which provides a measurement of intrinsic strength and failure strain of carbon fibres, is evaluated. This method, applied to linear elastic material, is based on a mathematical framework resulting from flexure theory. The results obtained demonstrate that for the carbon fibres studied those with the lowest value of stress concentration factor are characterised by an intrinsic breaking strain, epsilon-f, of 3.25% and an intrinsic tensile strength, sigma-f, of 7.33 GPa.
