复合材料塔架包含一个固体钛核心钻孔周围的多孔烧结钛壳已被制造和测试弯曲沿着与原芯和塔架组成的多孔钛单独。新型外挂架的设计理念是增强骨和皮肤细胞的向内生长，预期用于肢体假体的直接骨骼附着，考虑到对残余骨的持久锚固要求以及对安全皮肤-植入物密封的需求。确定了载荷-位移阈值，之后多孔组件的完整性可能会受损。该复合材料塔架的抗弯强度和刚度基本上大于仅由多孔钛构成的塔架的抗弯强度和刚度。固体插入物中的钻孔已被证明对塔架的弯曲强度几乎没有影响，同时满足装置的总渗透性要求，以实现不受限制的细胞向内生长。塔架的预测强度和相关的失效模式与测量结果非常吻合。
Composite pylons containing a solid titanium core with drilled holes surrounded by a porous sintered titanium shell have been fabricated and tested in bending along with the raw cores and pylons composed of the porous titanium alone. The new pylons were designed with the concept of enhanced ingrowth of bone and skin cells and are intended for direct skeletal attachment of limb prostheses considering requirements for long-lasting anchorage to the residuum bone and a need for a safe skin-implant seal. Load-displacement thresholds were determined after which the integrity of the porous component may be compromised. The composite pylons have a flexural strength and stiffness substantially greater than that of pylons composed of the porous titanium alone. The drilled holes in the solid insert have been shown to have virtually no effect on the flexural strength of the pylon, while meeting a requirement for total permeability of the device for unrestricted cell ingrowth. The predicted strength of the pylons and associated failure modes are in close agreement with those measured.
