Abstract

Non-planar additive manufacturing (AM) demonstrates great potential in enhancing interlayer bonding force and surface smoothness of parts, offering a more flexible design and manufacturing approach for continuous fiber composites to fully exploit material capabilities. This study developed a three-axis printer utilizing an adjustable fiber printing head that can achieve non-planar slicing (NPS) AM of pre-impregnated continuous fibers. The research delves into the influence of deposition inclined angle on the surface roughness of printed samples, enabling the design and printing of NPS samples using continuous carbon fiber (CF), glass fiber (GF), and hybrid fiber composites. The investigation also assesses bending failure morphologies of the printed parts and validates the efficacy of the NPS method through the fabrication of the double-sinusoidal curved surface structure and spherical surface grid structure. The results indicated that maintaining a deposition inclined angle below 15° is crucial to ensure surface accuracy in continuous fiber printed parts. Curved surface bending samples printed with NPS method exhibit substantial enhancements in bending performance and surface accuracy compared to those produced using planar slicing (PS). The NPS-CF sample achieves a remarkable increase of over 170% in maximum bending force and a 63% reduction in surface roughness compared to the PS-CF sample.

使用三轴打印机对预浸渍连续纤维增强复合材料进行非平面增材制造
非平面增材制造(AM)在增强层间结合力和零件表面光滑度方面具有巨大潜力,为连续纤维复合材料提供了一种更灵活的设计和制造方法,以充分发挥材料的性能。本研究开发了一种利用可调纤维打印头的三轴打印机,可实现预浸渍连续纤维的非平面切片(NPS)AM。研究深入探讨了沉积倾斜角对打印样品表面粗糙度的影响,从而能够使用连续碳纤维 (CF)、玻璃纤维 (GF) 和混合纤维复合材料设计和打印 NPS 样品。研究还评估了打印部件的弯曲破坏形态,并通过制造双正弦曲线表面结构和球形表面网格结构验证了 NPS 方法的有效性。结果表明,保持低于 15° 的沉积倾斜角对于确保连续纤维打印部件的表面精度至关重要。与平面切片法(PS)相比,采用 NPS 法打印的曲面弯曲样品在弯曲性能和表面精度方面都有显著提高。与 PS-CF 样品相比,NPS-CF 样品的最大弯曲力显著提高了 170%,表面粗糙度降低了 63%。
