| 中文摘要: |
| 创伤、肿瘤切除等引起的成人颅骨缺损高发，临床上对个性化人工颅骨植入体有较大的需求，而钛合金等金属材料人工颅骨植入体存在热学、力学性能与骨不匹配等诸多弊端，聚醚酮酮（PEKK）材料具有与人体骨组织相近的热学和力学性能，以及优异的耐磨性、稳定的物理化学性能和良好的生物相容性，用于颅骨植入体非常适合。本文基于拉伸实验数据，构建了PEKK的Johnson-Cook本构模型，并通过PEKK人工颅骨的热压成型有限元仿真，模拟了不同成型温度和压边力下的成型过程，获得了最佳热压成型工艺参数，最后通过PEKK热压成型实验验证了个性化人工颅骨植入体成型工艺的效果。 |
| 英文摘要: |
| The prevalence of adult skull defects caused by trauma, tumor resection, and other factors necessitates the need for patient-specific artificial cranial implants in clinical practice. Traditional metal materials, such as titanium alloys, often exhibit mismatches in thermal and mechanical properties compared to nature bone, prompting the exploration of alternative materials. Polyether-ketone-ketone (PEKK) material has emerged as a promising candidate due to its similarity to human bone tissue in thermal and mechanical properties, exceptional wear resistance, stable physical and chemical properties, and good biocompatibility. This study aims to construct a Johnson-Cook constitutive model for PEKK based on tensile experimental data, and subsequently simulate the hot-pressing forming process for PEKK patient-specific cranial implants under varying forming temperatures and blank holding forces using finite element simulation. The optimization of hot-pressing forming parameters is conducted to obtain the most suitable conditions for PEKK cranial implant fabrication, and the efficacy of the proposed forming process is verified through PEKK cranial implants forming experiments. |
