Data underlying the article "Polymer-Metal Interactions and Their Effect on Tool-Ply Friction of C/PEKK in Melt"

This data package provides all data and figures presented in the ESAFORM2024 conference paper: "Polymer-Metal Interactions and Their Effect on Tool-Ply Friction of C/PEKK in Melt." The purpose of the performed experiments was to identify the cause for the increase in friction between mild steel and APC in melt with dwell time. Friction experiments were performed on the following contact pairs i) APC vs. mild steel, ii) APC vs. mild steel with release coating, iii) APC vs. mild steel with additional PEKK film inserted at the interface, iv) APC vs. polyimide film, v) APC vs. stainless steel. The dwell time between closing of the pressure platens and executing the sliding motion in the friction tester was varied between 2.5, 5.0 and 10.0 minutes. DSC experiments were performed on tape material extracted from friction specimens and on as-received tape material to identify possible chemical changes during the friction measurements. Finally, SEM/EDX was used to analyze the fracture surface of of the samples. The dataset contains tool-ply friction measurements, differential scanning calorimetry data, and SEM/EDX images for UD C/PEKK (Solvay APC) against several tool materials. The scripts for processing the data are included as well.

本数据包包含ESAFORM2024会议论文《熔融状态下C/PEKK的聚合物-金属相互作用及其对铺层-模具摩擦的影响》中呈现的全部数据与图表。本次实验旨在探明低碳钢与熔融态APC间摩擦系数随保压时间延长而升高的原因。摩擦实验针对以下5组接触副开展：i）APC与低碳钢；ii）带有脱模涂层的低碳钢与APC；iii）界面处额外插入PEKK薄膜的低碳钢与APC；iv）聚酰亚胺薄膜与APC；v）不锈钢与APC。摩擦试验机中，压盘闭合至执行滑动动作之间的保压时间设置为2.5、5.0及10.0分钟三个梯度。针对从摩擦试样中提取的胶带材料与原始供货态胶带材料开展差示扫描量热（Differential Scanning Calorimetry, DSC）实验，以探究摩擦测试过程中是否发生化学变化。最后，采用扫描电子显微镜/能量色散X射线光谱（Scanning Electron Microscopy/Energy Dispersive X-ray Spectroscopy, SEM/EDX）对样品的断口表面进行分析。本数据集包含单向C/PEKK（Solvay APC）与多种模具材料配对的铺层-模具摩擦测量数据、差示扫描量热数据以及SEM/EDX图像。同时附带数据处理脚本。
