Investigation of the effect of wrinkle features on wind turbine blade sub-structure strength

Abstract: Wrinkles are known to have a strong knock-down on the mechanical performance of structures made from composite materials. Here, static tensile tests were conducted to investigate the effect of wrinkle features on the strength of a wind turbine blade sub-structure, representative of a blade root feature. A pultruded tapered insert is embedded in each sub-structure and the wrinkle is in close vicinity to the termination of the tapered insert. Each of the tested sub-structures was then numerically modelled using … Show more

“…All presented results from wrinkled sub-structures in the parametric study are numerical. A thorough comparison of numerical and experimental results for wrinkled sub-structures are presented in [13] None of the studied parameters are by themselves enough to determine the knock-down caused by the wrinkle. The average wrinkle angle can thus not be used on its own to determine the knock-down.…”

“…Based on this, it is assumed that the model can be used to predict the behaviour of a similar sub-structure with different variations of wrinkles included. Further comparison between experiments and numerical models are shown in [13].…”

“…Second, defects of the draping, the most prominent of which is wrinkling, can lead to drastic deterioration of the load-carrying ability of the consolidated part and can cause part rejection. Some studies have analysed the influence of the presence of wrinkles, created during manufacturing, on the mechanical performance of the composite [18,19,20,21]. A recent review [22] demonstrates that the presence, pattern and intensity of wrinkling can be accurately modelled once the constitutive model of the reinforcement is identified.…”

“…Some studies have been conducted on the influence of the manufacturing processes on the mechanical characteristics of composites [ 15 , 16 , 17 ]. The influence of defects and in particular of wrinkles and waviness on the mechanical characteristics of composites were analysed in [ 18 , 19 , 20 , 21 ].…”
