复合材料在航空航天、海军、汽车、建筑、导弹和国防技术等行业的高性能材料和产品的应用中发挥着越来越重要的作用。值得注意的是，取向纤维复合材料由于其有利的属性（如高强度重量比和受控的各向异性）而获得了大量关注。尽管如此，纤维排列不均匀、基体材料中的纤维聚集以及纤维体积的限制仍然存在挑战，阻碍了定向纤维增强复合材料的大规模生产。在这项研究中，我们提出了一种新的方法来3D打印重负载碳和尼龙复合材料中均匀排列的短纤维增强材料。利用快速和精确的增材制造潜力，挤出过程通过剪切力诱导碳纤维（CF）在长丝中对齐。创建的3D打印结构显示出令人印象深刻的定制潜力。与原始尼龙结构相比，它们始终表现出改善的机械和热性能。我们在聚合物复合材料中生产均匀分散和排列的短纤维增强材料的方法有望推动高性能复合材料和部件的设计和制造进步。
Composites play progressively significant roles across a spectrum of applications involving high‐performance materials and products within industries such as aerospace, naval, automotive, construction, missiles, and defense technology. Notably, oriented fiber composites have garnered substantial attention due to their advantageous attributes like a high strength‐to‐weight ratio and controlled anisotropy. Nonetheless, challenges persist in uneven fiber alignment, fiber clustering within the matrix material, and constraints on fiber volume, impeding the mass production of oriented fiber‐reinforced composites. In this study, we present a novel approach to 3D printing of uniformly aligned short fiber reinforcement in a composite of heavily loaded carbon and nylon. Capitalizing on the additive manufacturing potential of rapidity and precision, the extrusion process induces carbon fiber (CF) alignments in filaments via shear forces. The 3D‐printed structures that were created displayed impressive potential for customization. They consistently demonstrated improved mechanical and thermal properties when compared to the original nylon structures. Our methodology for producing uniformly dispersed and aligned short fiber reinforcement in polymer composites promises to propel the advancement of design and manufacturing for high‐performance composite materials and components.
