Supplementary data for the paper: Modeling the effect of temperature and pressure on the peak and steady-state ply-ply friction response for UD C/PAEK tapes

The dataset contains supplementary data for the accepted paper: 'Modeling the effect of temperature and pressure on the peak and steady-state ply-ply friction response for UD C/PAEK tapes' to be published in Composites Part A: Applied Science and Manufacturing. The dataset consists of ply-ply friction tests for UD C/PEEK and C/LM-PAEK tape in melt using a purpose-built friction tester, which simulates the response during actual hot press forming of thermoplastic matrix composites. Typically, the material response exhibits a peak followed by a steady-state friction depending on the applied rate. A range of sliding rates was measured at constant temperature and normal pressure conditions to construct a flow curve of the peak and steady-state shear stress versus applied rate, showing the rate-dependency in a comprehensible manner. Different temperature and normal pressure conditions were considered to investigate the effect of temperature and normal pressure on the friction response. The experimental procedure is outlined and an overview of the used specimens with the test conditions is provided. Our modeling work to predict the peak and steady-state friction for UD TPC tape in melt as presented in an earlier publication (DOI: 10.1016/j.compositesa.2022.107185) is extended to include the effect of temperature and normal pressure. The dataset includes the scripts for the shear flow model as well as the required matrix viscosity data. The Matlab scripts are named according to the figures as shown in the mentioned paper.

本数据集为已录用论文《Modeling the effect of temperature and pressure on the peak and steady-state ply-ply friction response for UD C/PAEK tapes》的补充数据，该论文将发表于《Composites Part A: Applied Science and Manufacturing》（《复合材料A辑：应用科学与制造》）。本数据集包含采用定制摩擦测试仪开展的熔融态单向碳纤维/聚醚醚酮带材（UD C/PEEK）与单向碳纤维/低熔点聚芳醚酮带材（UD C/LM-PAEK）的层间摩擦试验数据，该测试可模拟热塑性基体复合材料实际热压成型过程中的界面响应。通常而言，材料的摩擦响应会先出现峰值，随后进入稳态阶段，该特性取决于施加的滑动速率。研究团队在恒定温度与法向压力条件下，对一系列滑动速率开展了测试，以此构建峰值与稳态剪切应力随滑动速率变化的流动曲线，以清晰直观的方式展现摩擦响应的速率依赖性。此外，本研究还设置了不同的温度与法向压力条件，以探究其对层间摩擦响应的影响。文中详细阐述了试验流程，并提供了所用试样与试验条件的概览。本团队此前发表的一项研究（DOI: 10.1016/j.compositesa.2022.107185）中，已提出熔融态单向热塑性复合材料带材的峰值与稳态摩擦预测模型，本数据集将该模型拓展至纳入温度与法向压力的影响维度。数据集还包含剪切流动模型的代码以及所需的基体粘度数据，所有Matlab脚本均按照上述论文中对应图表的编号进行命名。
