Preparation method of medical artificial bone
The invention relates to a preparation method of a medical artificial bone. The preparation method is characterized by comprising the following steps: preparing a carbon fiber woven large blank; carrying out densification treatment on the carbon fiber woven large blank to obtain a carbon/carbon composite material blank; cutting the carbon/carbon composite material green body into a plurality of small green bodies; precisely cutting, polishing and forming the small green body to prepare a medical artificial bone prefabricated body; carrying out densification treatment and surface polishing on the medical artificial bone preform in sequence, so that the density and the mechanical strength of the medical artificial bone preform meet index requirements; and finely trimming the medical artificial bone preform to obtain a medical artificial bone product. According to the preparation method of the medical artificial bone, the manufacturing difficulty is low, the product quality is stable, the number of defective products is extremely small, the production efficiency is greatly improved, and the production cost is reduced; in addition, the carbon/carbon composite material can be processed into a medical artificial bone with a complex structure, and the application range of the carbon/carbon composite material in the field of artificial bones is expanded.
本发明涉及一种医用人造骨的制备方法，其特点在于其制备过程包括如下步骤：准备碳纤维编织大坯料；将碳纤维编织大坯料进行致密化处理，得到碳/碳复合材料坯体；将碳/碳复合材料坯体切割成多个小坯体；将小坯体进行精密切割打磨成型，制成医用人造骨预制体；对医用人造骨预制体依次进行致密化处理、表面打磨，以使医用人造骨预制体的密度和机械强度符合指标要求；将医用人造骨预制体精修得到医用人造骨产品。本发明提供的医用人造骨的制备方法，制造难度低、产品质量稳定、残次品极少，极大提高生产效率、降低生产成本；此外还能够加工成结构复杂的医用人造骨，扩大了碳/碳复合材料在人工骨骼领域的应用范围。
