We conducted compressive tests with coupon specimens observing failure of quasi-isotropic CFRP laminates. High speed imaging has been employed to find the location of initial fracture and illustrate the subsequent damages of the laminates.

Carbon-fibre/epoxy T800SC-24kf laminates with stitch thread of vectran 200d with different stitch density (0.11mm-2 and 0.028mm-2) has been analyzed for deformation behavior under in-plane tensile loading based on continuum mechanics.

This paper focuses on 'micro-local' scale modelling for tufted composites. The characterisation of the mode I bridging law of single carbon tufts is reported here, and a strategy for model development is proposed.

Mode II intralaminar delamination fracture toughness was firstly investigated. The intralaminar fracture toughness of interlayer-toughened CFRP was almost identical to the interlaminar and intralaminar fracture toughness of non-toughened CFRP.

The potential of an adaptive shell element formulation is shown, where delamination cracks are automatically introduced by an adaptive enrichment of the displacemnt field. A method to improve the transverse stresses in shells is also discussed.

Cohesive zone modelling is used to study delamination. A secondary crack can open when the peak traction value of its cohesive law is less than that of the primary crack and the layer between the two interfaces is sufficiently thin.
