Titel
The interlaminar shear strength of carbon fibre-reinforced carbon -CFC- - differences between various experimental methods
Abstract
The interlaminar shear strength (ILSS) is one of the most important mechanical properties of laminated fibre-reinforced materials, because it influences significantly all the other strength values and the failure behaviour. The ILSS of laminated composites is usually measured by loading short beams in a three-point-bending-arrangement with a span to depth ratio of s/d = 5. However, there are some doubts related to the usefulness of bending tests for determining real characteristic material values. Therefore, the failure behaviour and the stress distribution in short beams were investigated experimentally and numerically. Furthermore, these shear strength values were compared with results obtained by other shear test methods, e.g. slant-shear-, Iosipescu- and tensile-shear-tests.
