Supplementary data for the paper: A state-rate model for the transient wall slip effects in ply-ply friction of UD C/PAEK tapes in melt

The dataset contains supplementary data for the accepted paper: 'A state-rate model for the transient wall slip effects in ply-ply friction of UD C/PAEK tapes in melt' 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. The friction response for different sliding rates, while keeping the test temperature and normal pressure constant, is included as was measured in our earlier work (DOI: 10.1016/j.compositesa.2022.107185). The experimental procedure is outlined and an overview of the used specimens with the test conditions is provided. Typically, the response exhibits a peak followed by a steady-state friction depending on the applied rate. We extended our earlier modeling work, which focused only on the prediction of the peak and steady-state friction, to describe the full transient friction response by combining a White-Metzner viscoelastic fluid with a state-rate model to describe the evolution of slip at the fiber-matrix interface, gradually relaxing the shear stress with the ongoing deformation. The dataset includes the scripts used to process and plot the experimental data, to compute the response of the transient friction model as well as to process the required matrix viscosity data (part of earlier work). The matrix interlayer thickness distributions, as present at the ply-ply interface, are added, which also originate from our earlier work. The Matlab scripts are named according to the figures as shown in the mentioned paper.

本数据集为已接收论文《熔融状态下单向（UD）碳纤维/PAEK带材层间摩擦瞬态壁滑移效应的状态速率模型》（将发表于《Composites Part A: Applied Science and Manufacturing》）的补充数据。数据集包含采用定制化摩擦测试仪开展的熔融状态下单向碳纤维/PEEK及碳纤维/LM-PAEK带材的层间摩擦试验数据，该测试仪可复现热塑性基复合材料实际热压成型过程中的力学响应。本数据集收录了本团队前期研究（DOI: 10.1016/j.compositesa.2022.107185）中，固定试验温度与法向压力条件下测得的不同滑动速率下的摩擦响应数据。数据集同时提供了试验流程概述，以及所用试样与试验条件的汇总信息。通常，该摩擦响应会先出现峰值，随后进入稳态摩擦阶段，且稳态摩擦水平与施加的滑动速率密切相关。本团队将此前仅聚焦于峰值与稳态摩擦预测的建模工作进行了拓展，通过结合White-Metzner粘弹性流体与状态速率模型，描述纤维-基体界面处的滑移演化过程，并结合持续变形过程中剪切应力的逐步松弛，实现了完整瞬态摩擦响应的建模。本数据集包含用于处理、绘制试验数据，计算瞬态摩擦模型响应，以及处理所需基体粘度数据（前期研究的一部分）的脚本文件。数据集同时收录了层间界面处的基体层厚度分布数据，该数据同样源自本团队的前期研究。本数据集内的Matlab脚本均按照上述论文中所示图表的编号进行命名。
