What is The Effect of Fibre Misalignment in an Impregnated Fibre Bundle on Stress Concentrations about?
This work investigates the stress redistribution around a broken fibre in a unidirectional impregnated fibre bundle accounting for misalignment of fibres. The study reveals, a statistically significant increase in stress concentration factor (SCF) within misaligned bundles. The effect of fibre misalignment is more pronounced for high fibre volume fraction (VF) and for the nearest neighbour fibres (NNFs) to the broken one. The peak of the SCF graphs shows a significant increase about 16%, 33%, and 55% for VF30%, VF50%, and VF60%, respectively. This implies that the influence of fibre misalignment is more localised, resulting in stronger SCF in the NNFs. Ineffective lengths at applied strain 2% do not change in the case of fibre misalignment in comparison with the case of aligned fibres. This is linked to matrix yielding, as at applied strain 0.1% the ineffective length increases for the misaligned case by 12-30%, depending of fibre volume fraction.
