碳纤维板塑复合材料的力学性能对增强纤维的内部几何形状非常敏感。在本研究中，采用不同厚度的胶带制备了具有优异力学性能的新型CF-SMCs，即短切碳纤维带增强热塑性塑料（CTTs）。通过实验和分析两种方法评估了带形对CTTs拉伸性能的影响。采用两种基于x射线辅助计算机断层扫描（CT）的方法分析了胶带厚度对CT内部几何形状的影响。基于x射线显微ct分析获得的纤维取向数据，采用改进的Mori-Tanaka模型。结果表明：随着面外取向的增加，薄膜的拉伸性能显著降低，且厚度越厚，薄膜的拉伸性能越差。此外，随着胶带厚度的增加，拉伸性能也有较大的变化。发现两种x射线微ct方法适合于内部几何形状的可视化和定量分析。发现胶带厚度与拉伸性能之间存在相关性。最后，使用Mori-Tanaka模型和纤维取向数据进行的模拟结果与拉伸模量的实验结果相似，但强度的结果与实验结果存在差异。
The mechanical properties of carbon fiber sheet molding compounds (CF-SMCs) are sensitive to the internal geometry of the reinforcing fibers. In this study, novel CF-SMCs with outstanding mechanical performance, namely, chopped carbon fiber tapes reinforced thermoplastics (CTTs), were fabricated using tapes with different thicknesses. The effects of the tape morphology on the tensile properties of the CTTs were evaluated both experimentally and analytically. Two X-ray-aided computed tomography (CT) based methods were adopted to analyze the effects of the tape thickness on the internal geometry of the CTTs. The modified Mori–Tanaka model was used based on the fiber orientation data obtained from the X-ray micro-CT analyses. The results showed that the tensile properties decreased significantly with an increase of the out-of-plane misorientation, which is more intensive for thicker tapes. In addition, the tensile properties showed greater variations as the tape thickness was increased. The two X-ray micro-CT methods were found to be suitable for visualizing and quantitatively analyzing the internal geometries. Correlations were found between the tape thickness and the tensile properties. Finally, the results of the simulations performed using the Mori–Tanaka model and the fiber orientation data were found to be similar to those of the experiments in tensile moduli, but the results for strength deviate from the experiments.
