MODE I CRACK PATH TRANSITIONS IN UNIDIRECTIONAL CARBON FIBRE COMPOSITES ANALYSED USING IN SITU 3D COMPUTED TOMOGRAPHY AND THE EXTENDED FINITE ELEMENT METHOD
Abstract
Synchrotron Radiation Computed Tomography has been used to make time-series observations of crack transition in a particle toughened unidirectional carbon fibre reinforced polymer composite system during an in situ wedge opening Mode I delamination test. Furthermore, a finite element model combining both cohesive elements and the eXtended Finite Element Method has been used to explore factors contributing to crack transition. The synchrotron data reveals features such as tow gaps and resin pockets, which could be significant in crack transition A lateral crack transition to the ply was observed suggesting the need for three-dimensional analysis of the crack transition problem. The finite element modelling suggests variation in interlayer thickness is critical in crack transition where a thicker more uniform interlayer favoured crack propagation in the interlayer, whereas variability in the interlayer results in transition of the crack to the fibre interface and ply region of the composite around the thinnest regions. © 2022 Ball et al.
