T-T fatigue damage data in carbon/epoxy [04/90n/04] using UTPs

This record presents the complete experimental dataset derived from the study of the experimental observation of the onset of transverse damage and its progression in two different cross-ply laminates under tension–tension cyclic loading. The first dataset relates to a [04/903/04] laminate made of plies with conventional thickness (150 g/m2), and the second relates to a [04/90/04] laminate with a single ultra-thin 90⁰ ply (30 g/m2).
