Ply-strength depends on ply-thickness (also known as in-situ effect)

Out-of-plane loads induce shear cracks and delaminations

Thin-plies increase several in-plane mechanical properties because of the in-situ effect

Thin-plies display brittle failure mechanisms

\midrule
Interleaving polyamide veils with a relatively high fibre areal weight enhances impact resistance, tolerance and interlaminar fracture toughness
\smallskip
The improvement comes with a penalty of tensile and compressive properties
& Few studies incorporate veils with low fibre areal weight
\smallskip
No study toughens thin-ply laminates
\smallskip
Few studies connect veil fibre architecture and mechanical properties
