In the field of textile technology, this study centers on towpreg—an integral component utilized in production techniques like tape laying and filament winding. Here, fibers are pre‐coated with resin, typically epoxy but not exclusively. Notably, towpreg retains a partially cured state, maintaining tackiness throughout the processing stages. The ultimate quality of the product manufactured with this towpreg is highly dependent on this initial material. This research highlights the importance of considering various factors that impact product quality. While not exhaustive, a systematic analysis of diverse towpreg parameters, including tack, resin content, and width, is provided. The work encompasses findings, challenges, and insights derived from towpreg manufacturing, incorporating the investigation of various experimental methodologies. The study also evaluates methodologies for laminated coupon production with towpreg, assessing their applicability in characterizing filament‐wound components. Although the article seems like a review, the authors aim to give a clear and holistic picture in one work instead of spreading information across many articles.Highlights Techniques for the quantification of towpreg tack are presented. Resin content distribution along towpreg length is presented. Towpreg width variation was investigated, seen to be one of the major causes for the gaps and voids in a filament wound composite. Coupon‐level characterization of towpreg through filament winding approach is presented. Other filament winding parameters influencing the quality of the manufactured composite are discussed.

纤维缠绕应用的丝束聚酯纤维制造和表征

在纺织技术领域，这项研究的重点是丝束浸布——一种用于铺带和长丝缠绕等生产技术的整体组件。在这里，纤维预先涂有树脂，通常是环氧树脂，但不限于此。值得注意的是，丝束浸料保持部分固化状态，在整个加工阶段保持粘性。使用这种丝束浸布制造的产品的最终质量很大程度上取决于这种初始材料。这项研究强调了考虑影响产品质量的各种因素的重要性。虽然并不详尽，但提供了对各种丝束浸料参数的系统分析，包括粘性、树脂含量和宽度。这项工作涵盖了来自丝束预浸料制造的发现、挑战和见解，并结合了对各种实验方法的研究。该研究还评估了使用丝束浸渍材料生产层压试样的方法，评估了它们在表征纤维缠绕组件方面的适用性。尽管这篇文章看起来像是一篇评论，但作者的目的是在一篇作品中给出清晰、全面的描述，而不是在多篇文章中传播信息。 提出了丝束预浸料粘性的量化技术。 给出了沿丝束浸料长度的树脂含量分布。 研究了丝束浸料宽度变化，认为这是长丝缠绕复合材料中出现间隙和空隙的主要原因之一。 提出了通过纤维缠绕方法对丝束浸料进行优惠券级表征。 讨论了影响所制造复合材料质量的其他纤维缠绕参数。
