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).本数据集完整呈现了两项实验研究的全部观测数据，两项研究均针对两种不同正交铺层层合板在拉-拉循环载荷条件下的横向损伤萌生与扩展过程开展实验观测。其中第一组数据集对应铺层结构为[04/903/04]的层合板，其所有铺层均采用常规厚度（150 g/m²）；第二组数据集对应铺层结构为[04/90/04]的层合板，其仅包含一张超薄90°铺层（30 g/m²）。
