In this study, we focused on fabrication and characterization of three-dimensional carbon fiber-reinforced polyetheretherketone (C3-D/PEEK) composites for orthopedic applications. We found that pre-heating of 3-D fabrics before hot-pressing could eliminate pores in the composites prepared by 3-D co-braiding and hot-pressing techniques. The manufacturing process and the processing variables were studied and optimum parameters were obtained. Moreover, the carbon fibers were surface treated by the anodic oxidization and its effect on mechanical properties of the composites was determined. Preliminary cell studies with mouse osteoblast cells were also performed to examine the cytocompatibility of the composites. Feasibility of the C3-D/PEEK composites as load-bearing bone fixation materials was evaluated. Results suggest that the C3-D/PEEK composites show good promising as load-bearing bone fixations.
在这项研究中，我们专注于制造和表征用于骨科应用的三维碳纤维增强聚醚醚酮（C3-D/PEEK）复合材料。我们发现，在通过三维编织和热压技术制备复合材料之前对三维织物进行预热，可以消除复合材料中的孔隙。研究了制造工艺和加工变量，并获得了最佳参数。此外，通过阳极氧化对碳纤维进行了表面处理，并确定了其对复合材料力学性能的影响。还进行了初步的小鼠成骨细胞细胞研究，以检查复合材料的细胞相容性。评估了 C3-D/PEEK 复合材料作为承重骨固定材料的可行性。结果表明，C3-D/PEEK 复合材料作为承重骨固定材料具有良好的应用前景。
