本文介绍了在陶瓷光固化快速成型中利用剪切诱导对准方法。横向振荡机制，结合3D打印墙图案，用于产生必要的剪切力，以使纤维在所需方向上对齐。首先，印刷半圆形通道图案以评估壁方向和振荡方向之间的差异对纤维排列的影响。在此基础上，测试了镍包碳纤维和陶瓷纤维增强体对陶瓷基体抗弯强度的影响。结果表明，与随机分布的样品相比，剪切诱导排列进一步提高了弯曲强度。与随机取向的样品相比，具有1.0重量%碳纤维负载的对齐样品的弯曲强度提高了约90%，与未增强的样品相比提高了约333%。最后，对弯曲强度测试样本的断裂表面形态进行了评价。断裂机制主要为纤维拔出。
This paper accounts for utilization of shear induced alignment method during ceramic stereolithography. Lateral oscillation mechanism, combined with 3d printed wall pattern, was employed to generate necessary shear to align fiber in desired direction. First, semicircular channel pattern was printed to assess the effect of difference between wall direction and oscillation direction on the fiber alignment. Then, flexural strength of ceramic matrix was tested with nickel coated carbon fiber and ceramic fiber reinforcements. The results demonstrated that the shear induced alignment further improves the flexural strength compare to randomly distributed samples. Flexural strength of aligned samples with 1.0 wt% carbon fiber loading was improved by ~90% compared to randomly orientated samples and by ~333% compared to unreinforced samples. Finally, fracture surface morphology of the flexural strength test specimens was evaluated. The main fracture mechanism was observed as fiber pull-out.
