A multiscale fibre break model (FBM) developed at Mines ParisTech has shown relatively good comparison to the experimental observations by computed tomography (CT) technique, however, it was mentioned that a better description of T700 fibre properties is necessary as it may affect the accumulation process of the fibre breaks. Therefore, further study on fibre strength characterisation can provide insights on the actual fibre strength variation and thereby also improve the quality of the failure predictions of the FBM. In this paper, an attempt has been made to understand the variability in the predicted failure of CPVs using the FBM, as a result of the expected variability in the input fibre properties.
