Delamination growth characterization under mixed Mode I-Mode II loading
Original language description
The report describes methods and results of the delamination growth in a carbon fibre-reinforced polymer composite under mixed mode I (opening) – mode II (shear) quasi-static and fatigue loading. The characterization of material parameters on mixed mode bending (MMB) specimens was needed for crack growth modelling purposes. Simultaneously, the effect of the optical fibre inserted in the laminate was studied. This report summarizes the results of 15 quasi-static and 3 fatigue specimens tested in 3 different mode mixtures – 25%, 50% and 80%. The fracture toughness was increasing with the increasing mode mixture. The effect of the optical fibre on fracture toughness was significant. The scatter of values was increasing with the GII mode preference. The curves of crack growth rate vs. strain energy release rate were obtained and fitted by the Paris law.
