Mode II Delamination Test Results for Unidirectional and Multidirectional Carbon/Epoxy Composite Laminates Using End-Loaded Split

This dataset collects the test results of Mode II delamination for unidirectional and multidirectional Carbon Fibre Reinforced Polymer (CFRP) composite laminates using the End-Loaded Split (ELS) test configuration. The experiments were performed under the guidance of the test standard ISO 15114 (2014). The composite laminates consist of 16 layers manufactured with unidirectional prepreg. In total, 6 types of specimens with different layups and initial delamination interfaces were tested. The force-displacement responses, delamination length and area measurements, and Acoustic Emission (AE) events are stored in the dataset. The calculated R-curve based on the J-integral method is also provided, as well as the energy dissipation per area increment for determining the total Energy Release Rate (ERR).

本数据集收录了采用端部加载劈裂（End-Loaded Split, ELS）试验构型，针对单向及多向碳纤维增强聚合物（Carbon Fibre Reinforced Polymer, CFRP）复合层板开展的II型层间脱层试验结果。所有试验均严格遵循ISO 15114（2014）试验标准实施。该复合层板由16层单向预浸料制备而成，本次试验共测试了6种具备不同铺层方式与初始脱层界面的试样。数据集涵盖力-位移响应曲线、脱层长度与面积测量数据，以及声发射（Acoustic Emission, AE）事件记录。此外，数据集还提供了基于J积分法计算得到的R曲线，以及用于求取总能量释放率（Energy Release Rate, ERR）的单位面积增量耗散能。
