Data from: An experimental study on the manufacture and characterisation of in-plane fibre-waviness defects in composites

A new method has been developed for creating localised in-plane
fibre-waviness in composite coupons and used to create a large batch of
specimens. This method could be used by manufacturers to experimentally
explore the effect of fibre-waviness on composite structures both directly
and indirectly to develop and validate computational models. The specimens
were assessed using ultrasound, digital image correlation and a novel
inspection technique capable of measuring residual strain fields. To
explore how the defect affects the performance of composite structures,
the specimens were then loaded to failure. Predictions of remnant strength
were made using a simple ultrasound damage metric and a new residual
strain-based damage metric. The predictions made using residual strain
measurements were found to be substantially more effective at
characterising ultimate strength than ultrasound measurements. This
suggests that residual strains have a significant effect on the failure of
laminates containing fibre-waviness and that these strains could be
incorporated into computational models to improve their ability to
simulate the defect.
