摘要整理
提出了一种采用超低熔融粘度聚合物的复合材料3D打印方法，相比传统粘度聚合物，该方法可实现更低的孔隙率和更高的强度。以连续碳纤维作为长丝的芯部，超低粘度聚合物（单独聚合物无法成丝）得以应用。本研究进行了聚醚醚酮/碳纤维（CF/PEEK）长丝挤出，并评估了熔融粘度对长丝中孔隙的影响。超低粘度聚合物（CF/PEEK 90 G）相比标准聚合物（CF/PEEK 450 G），长丝中的孔隙减少了92%。还评估了采用不同PEEK聚合物熔融粘度制备的3D打印CF/PEEK长丝的层间拉伸强度。CF/PEEK 90 G的层间拉伸强度相比CF/PEEK 450 G提高了116.8%。该研究表明，通过采用超低熔融粘度聚合物与连续碳纤维复合的策略，可以显著降低3D打印复合材料的孔隙缺陷，大幅提升层间力学性能，为高性能复合材料增材制造提供了新的技术途径。
