摘要

连续纤维增强热塑性复合材料(CFRTPCs)的三维打印具有灵活性和一步成型的优点,已被应用于复合材料复杂结构的成型。在本研究中,对梅塞施密特-伯尔考-布洛姆(MBB)梁和悬臂梁进行了特征点简化、合并和重新排列,以生成试样的单冲程打印路径。针对这些结构的有限元分析结果中的重要应力区域,提出了一种使用正交铺层的局部加固方法,该方法是通过在打印过程中升降打印头和调整纤维体积分数来实现的。经过实验验证和失效模式分析,路径规划显著提高了试样的峰值载荷和结构刚度,局部加固进一步提高了等效比强度和比刚度。该研究为复杂结构成型提供了一种结合参数调整的单冲程三维打印策略。

3D printing single-stroke path planning, local reinforcement and performance testing of MBB beams and cantilever beams
3D printing of continuous fiber reinforced thermoplastic composites (CFRTPCs) has been applied for the molding of composite complex structures due to the advantages of flexibility and one-step forming. In this study, feature points simplification, merging and rearrangement were accomplished for Messerschmitt-Bölkow-Blohm (MBB) beam and cantilever beam to generate single-stroke print paths for the specimens. For the significant stress areas in the finite element analysis results of these structures, a local reinforcement method using orthogonal layups was proposed, which was achieved by raising and lowering the print head and adjusting the fiber volume fraction during the printing. After experimental validation and failure modes analysis, the path planning significantly improved the peak load and structural stiffness of the specimens, and the local reinforcement further enhanced the equivalent specific strength and specific stiffness. This study provides a single-stroke 3D printing strategy for complex structure molding in conjunction with parameter adjustments.
