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、将发表于《复合材料A辑：应用科学与制造》（Composites Part A: Applied Science and Manufacturing）的论文《熔融态单向（Unidirectional, UD）碳/聚芳醚酮（C/PAEK）带材层间摩擦的瞬态壁滑移效应状态速率模型》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态单向碳/PEEK（UD C/PEEK）与单向碳/LM-聚芳醚酮（C/LM-PAEK）带材的层间摩擦试验数据，该测试仪可精准模拟热塑性基体复合材料实际热压成型过程中的受力响应。试验中保持测试温度与法向压力恒定，仅改变滑动速率，所得不同滑动速率下的摩擦响应数据取自我们此前的研究工作（DOI: 10.1016/j.compositesa.2022.107185）。本数据集概述了完整试验流程，并给出了所用试样参数与试验条件的详细说明。通常而言，摩擦响应会先出现峰值，随后进入稳态阶段，该行为受施加载荷速率的影响。我们拓展了此前仅聚焦于峰值与稳态摩擦预测的建模工作，将怀特-梅茨纳（White-Metzner）粘弹性流体模型与状态速率模型相结合，用以描述纤维-基体界面滑移的演化过程，并随着变形的持续逐步松弛剪切应力，从而实现完整瞬态摩擦响应的建模。数据集还包含用于处理、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（取自此前研究工作）的脚本代码。此外还提供了层间界面处的基体层间厚度分布数据，该数据同样来自我们此前的研究工作。本次所用Matlab脚本均按照上述论文中对应插图的编号进行命名。
