- For the first time in literature, a systematic investigation of the dynamic delamination failure of Z-pinned (or Through-Thickness-Reinforced) laminates is carried out at coupon (structural) scale under pure mode I, pure mode II and mixed-mode loadings. The study served as a testing protocol for an Innovate UK-Rolls Royce project to characterise novel composites for gas turbine fan blades at high strain rates, for which no testing standard exists so far. Another important takeaway is the excellent correlations between single-pin and coupon scale tests. This finding provided useful guidelines that simpler single-pin tests are sufficient to obtain toughness of Z-pinned composites
