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.

本金色开放获取（open-access gold）论文研究了热塑性自动化纤维铺放（Thermoplastic Automated Fiber Placement, TAFP）工艺中，工艺特异性缺陷对层压板质量与力学性能的影响。本次试样试板采用60wt%连续碳纤维增强聚苯硫醚制备。在完成TAFP铺层工序后，分别采用三种不同的固结工艺进行处理。研究中同时对铺层顺序、缺陷类型及缺陷尺寸进行了变量设置。试样拉伸测试依照DIN ISO 527标准执行，测试过程中使用GOM Aramis数字引伸计采集应变数据。压缩测试则参照ASTM-6484标准开展。本次提供的数据包含拉伸与压缩测试中试验机的原始采集数据；针对拉伸测试，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进行标识：每组参数集以XX-Y-Z-S格式命名，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。每个试验机数据文件包含5个被测试样的独立工作表，各工作表以内部测试编号与试样索引组合的形式命名。仅针对用于绘图与图像生成的试样，提供了对应的ARAMIS应变数据。作者通过主观比对应变测量结果与生成绘图，确保所选试样可代表对应组别的整体特性。
