This paper focuses on fabrication and characterization of knitted carbon/PEEK fabric composites for orthopedic bone plate application. Bending performance of the knitted carbon/PEEK composite bone plates was investigated with respect to two principal knitting directions (wale- and course-directions). As a result, the wale-direction knitted composite bone plates had much scattering in bending stiffness and maximum bending moment although they exhibited the same bending behavior as that of the course-direction specimens. In comparison with our previously developed braided composite bone plates, the knitted composite bone plates had 55-59% bending stiffness, 40-63% yield bending moment, and 54-77% maximum bending moment. However, the knitted composite bone plates showed higher deformability. Based on the results of the braided composite bone plates, it is considered that the knitted composite plate with 3.2mm thickness can be suitable for forearm or humerus treatment especially when damaged bones need higher deformation to encourage bone ossification.
本文着重于用于矫形骨板应用的针织碳/聚醚醚酮织物复合材料的制造与表征。针对两个主要针织方向（纵行和横列方向）研究了针织碳/聚醚醚酮复合骨板的弯曲性能。结果表明，纵行方向针织复合骨板在弯曲刚度和最大弯矩方面有很大的离散性，尽管它们与横列方向试样表现出相同的弯曲行为。与我们之前开发的编织复合骨板相比，针织复合骨板的弯曲刚度为55 - 59%，屈服弯矩为40 - 63%，最大弯矩为54 - 77%。然而，针织复合骨板显示出更高的可变形性。基于编织复合骨板的结果，认为厚度为3.2毫米的针织复合板可能适用于前臂或肱骨治疗，特别是当受损骨骼需要更高的变形以促进骨化时。
