Abstract

The growing demand for lightweight and robust materials drives the development of polymer-based and fiber-reinforced composites. Here, using short fibers offers several advantages; however, currently employed methods for producing short fibers, such as homogenization, result in a wide dispersion of dimensions in the produced fibers, which is an undesirable effect in composite materials. In this study, electrospinning is used to produce polymer short fibers directly. This research highlights, for the first time, the differences in the electrospinning process dynamics between short and continuous fibers. By adjusting parameters: voltage and distance, we control dimensions of short fibers below 1 µm in diameter and around 4 µm in length to a few microns in diameter and approximately 14 µm in length. Direct electrospinning of short fibers offers significant advantages, including a narrow size distribution and reproducibility compared to chopped continuous fibers with homogenization.

直接电纺短聚合物纤维：影响尺寸和质量的因素

对轻质坚固材料的需求日益增长，推动了聚合物基纤维增强复合材料的发展。然而，目前使用的生产短纤维的方法（如均质化）会导致生产的纤维尺寸分散，这在复合材料中是不可取的。本研究采用电纺丝技术直接生产聚合物短纤维。这项研究首次强调了短纤维和连续纤维在电纺丝过程动力学上的差异。通过调整电压和距离等参数，我们控制了直径低于 1 微米、长度约为 4 微米的短纤维尺寸，以及直径为几微米、长度约为 14 微米的短纤维尺寸。与均匀化切碎的连续纤维相比，直接电纺短纤维具有显著的优势，包括尺寸分布窄和可重复性好。

期刊介绍： Composites Part A: Applied Science and Manufacturing is a comprehensive journal that publishes original research papers, review articles, case studies, short communications, and letters covering various aspects of composite materials science and technology. This includes fibrous and particulate reinforcements in polymeric, metallic, and ceramic matrices, as well as 'natural' composites like wood and biological materials. The journal addresses topics such as properties, design, and manufacture of reinforcing fibers and particles, novel architectures and concepts, multifunctional composites, advancements in fabrication and processing, manufacturing science, process modeling, experimental mechanics, microstructural characterization, interfaces, prediction and measurement of mechanical, physical, and chemical behavior, and performance in service. Additionally, articles on economic and commercial aspects, design, and case studies are welcomed. All submissions undergo rigorous peer review to ensure they contribute significantly and innovatively, maintaining high standards for content and presentation. The editorial team aims to expedite the review process for prompt publication.
