在这项工作中，开发并研究了对齐不连续纤维复合材料（ADFRC）带作为新型3D打印长丝的前体。考虑到足够的纤维长度和高水平的对齐，ADFRC具有实现与连续纤维增强复合材料相当的机械性能的潜力，并且避免了与连续纤维相关的许多制造困难，例如，交叉、桥接和拐角半径约束。本文研究了它们在熔丝制造（FFF）技术中的潜在用途。进行热塑性基质的广泛向下选择过程，因为基质性质显著影响长丝的加工和性能。这产生了四种候选聚合物（ABS、PLA、尼龙、PETG），其用于使用高性能不连续纤维（HiPerDiF）技术和内部开发的连续固结模块制造Vf为12.5%的ADFRC胶带。拉伸刚度和强度分别高达30 GPa和400 MPa的记录，表明不连续的纤维长丝有可能与连续的纤维长丝竞争。
In this work, aligned discontinuous fibre composite (ADFRC) tapes were developed and investigated as precursors for a novel 3D printing filament. ADFRCs have the potential to achieve mechanical performance comparable to continuous fibre reinforced composites, given sufficient fibre length and high level of alignment, and avoid many of the manufacturing difficulties associated with continuous fibres, e.g., wrinkling, bridging and corner radii constraints. Their potential use for fused filament fabrication (FFF) techniques was investigated here. An extensive down-selection process of thermoplastic matrices was performed, as matrix properties significantly impact both the processing and performance of the filament. This resulted in four candidate polymers (ABS, PLA, Nylon, PETG) which were used to manufacture ADFRC tapes with a Vf of 12.5% using the high performance discontinuous fibre (HiPerDiF) technology and an in-house developed continuous consolidation module. Tensile stiffness and strength up to 30 GPa and 400 MPa respectively were recorded, showing that a discontinuous fibre filament has the potential to compete with continuous fibre filaments.
