PhD Related Data: THE ENHANCEMENT OF MECHANICAL DAMPING AND STIFFNESS TRADE-OFF USING UNIDIRECTIONAL CARBON FIBER REINFORCED POLYMER COMPOSITE INTERLEAVED WITH RECYCLED CARBON FIBER AND SHORT VIRGIN ARAMID FIBER NON-WOVEN MATS by Cephas Yaw Attahu

This research investigated incorporating recycled carbon fibers (rCFs) into carbon fiber reinforced polymer composites (CFRPs) for structural applications. The impacts of titanate coupling agent-L12 on the mats; the interleaved rCFs mat's numbers; their locations (the interleaved rCFs mat); the influence of the rCFs' lengths and their combinations (combining different rCF lengths); types (different rCF types); and their (rCFs) micro-hybridization with short virgin aramid fibers (vAFs) were all explored as part of the investigations. This project addressed and closed a significant gap in using rCFs for structural applications. The methodology used (the interleaving of UD fiber/epoxy prepreg with rCF non-woven mats) is the first of its kind. Furthermore, the final product (the best configuration, Laminate T) was very competitive: it was pegged against another novel composite material from an excellent source, and the results were very encouraging. Hosted here is the project's related raw dataset.

本研究旨在探讨将回收碳纤维（rCFs）融入碳纤维增强聚合物复合材料（CFRPs）中以应用于结构领域。研究内容涵盖了钛酸酯偶联剂-L12对基布的影响；交织层rCFs基布的数量；其位置（交织层rCFs基布）；回收碳纤维的长度及其组合（不同长度回收碳纤维的结合）；类型（不同类型的回收碳纤维）；以及它们（回收碳纤维）与短原纤维芳纶（vAFs）的微观混合作用。这些内容均为研究的一部分。本项目针对并填补了使用回收碳纤维于结构应用领域的重要空白。所采用的方法（将单向纤维/环氧预浸料与回收碳纤维非织造基布交织）为首次创新。此外，最终产品（最佳配置，层压板T）具有极高的竞争力：其性能与另一来自优秀来源的新型复合材料进行了对标，结果令人鼓舞。本平台提供该项目相关原始数据集。
