Effects of Defects on Laminate Quality and Mechanical Performance in Thermoplastic Automated Fiber Placement-based Process Chains

The corresponding paper (open-access gold) investigates the effects of process specific defects on the laminate quality and mechanical performance for the Thermoplastic Automated Fiber Placement (TAFP) process. The coupon panels were made of polyphenylene sulfide with 60 %wt. continous carbon fiber reinforcment. Subsequent to TAFP layup, three different consolidation processes were applied. Furthermore, stacking sequence, defect type and defect size were varied. Tensile testing of the specimens was conducted according to DIN ISO 527. A GOM Aramis digital extensiometer was used for strain recording. Compression testing was conducted in reference to ASTM-6484.
The data provided contains the raw data from the testing machine for both compression and tensile testing. For the latter, the export of the ARAMIS strain concantration measurements is provided as well.
Within all data sets, the specimens are refered to with the same nomenclature that is used in the paper. Each parameter set is addressed by XX-Y-Z-S, where XX is the consolidation process, Y is the stacking sequence, Z is the type of defect and S is the defects size.
Each testing machine data file contains all five specimen tested as seperate tab. The tabe are named with an internal testing number followed by the specimen index. The ARAMIS strain data is only provieded for the specimen that was considered for the plot and image generation. The authors did ensure that the selected specimen is representative for the corresponding group by subjective comparison of the strain measurements and plots.

本研究对应的金色开放获取（open-access gold）论文，探究了热塑性自动化纤维铺放（TAFP）工艺中特定工艺缺陷对层合板质量与力学性能的影响。试验板材采用质量占比60%的连续碳纤维增强聚苯硫醚（polyphenylene sulfide）制备。在TAFP铺层完成后，采用三种不同的固结工艺。此外，还对铺层顺序、缺陷类型与缺陷尺寸进行了变量设置。
试样拉伸试验依据DIN ISO 527标准开展，采用GOM Aramis数字引伸计（GOM Aramis digital extensiometer）进行应变数据采集；压缩试验则参照ASTM-6484标准执行。
本次提供的数据包含拉伸与压缩试验中试验机采集的原始数据。针对拉伸试验，还同步提供了ARAMIS应变集中测量结果的导出文件。
所有数据集内的试样均采用与论文一致的命名规则。每组参数通过XX-Y-Z-S格式标识，其中XX代表固结工艺，Y代表铺层顺序，Z代表缺陷类型，S代表缺陷尺寸。
每份试验机数据文件包含全部5个被测试样的测试数据，以独立工作表（tab）形式存储。工作表名称由内部试验编号与试样索引组合而成。
ARAMIS应变数据仅针对用于绘图与图像生成的试样提供。作者通过主观比对应变测量结果与可视化图表，确认所选试样可代表对应组别的试样特性。
