The socket plays an important role in prostheses by providing structural integrity and suspension to the distal thigh of an amputee. Heat accumulation and weight of the socket increase the energy consumption in the amputee. To overcome the same, widely used polyester-based sandwich-structured composite was reinforced with 0.2, 0.4, 0.6, 0.8, and 1 wt% multiwalled carbon nanotube (MWCNT) and analyzed for the thermal and mechanical properties. MWCNT added in a small weight proportion with polyester enhances the mechanical properties of the resulting nanocomposites as they have excellent mechanical and physical properties. The flexural and thermal property was evaluated as per ASTM D790 and ISO 22007-2 standard. It was noticed that the thermal property enhances with increase in wt% of MWCNT and mechanical properties decreased when more than 0.6 wt% MWCNT was reinforced. Hence, the sandwich-structured composite was prepared using polyester resin, 2 to 10 stockinette layers, fiberglass cloth, and 0.6 wt% of MWCNT. The thermal conductivity and flexural strength of 0.6 wt% MWCNT-reinforced sandwich-structured composite were enhanced upto 68.4% and 11.4% for 2-10 stockinette layers, respectively, while comparing to the unreinforced polyester sandwich-structured composite. The 0.6 wt% MWCNT-reinforced sandwich-structured composite may help in reducing the weight and heat build up in the socket. Hence, it is recommended to analyze further on their application in transfemoral socket preparation to bring down an amputee’s metabolic cost.

使用 PE/MWCNT 复合材料减轻经股骨承窝的重量和热量积累

承窝通过为截肢者的大腿远端提供结构完整性和悬挂在假肢中发挥重要作用。承窝的热量积聚和重量增加了截肢者的能量消耗。为了克服同样的问题，广泛使用的聚酯基夹层结构复合材料用 0.2、0.4、0.6、0.8 和 1 wt% 的多壁碳纳米管 (MWCNT) 增强，并分析了热性能和机械性能。MWCNT 与聚酯以小重量比例添加，可增强所得纳米复合材料的机械性能，因为它们具有优异的机械和物理性能。根据 ASTM D790 和 ISO 22007-2 标准评估弯曲和热性能。注意到热性能随着 MWCNT 重量百分比的增加而增强，当大于 0 时机械性能下降。6 wt% MWCNT 被增强。因此，夹心结构的复合材料是使用聚酯树脂、2 到 10 层长袜层、玻璃纤维布和 0.6 wt% 的 MWCNT 制备的。与未增强的聚酯夹层结构复合材料相比，0.6 wt% MWCNT 增强的夹层结构复合材料的热导率和弯曲强度分别提高了 68.4% 和 11.4%，对于 2-10 层袜子。0.6 wt% MWCNT 增强的夹层结构复合材料可能有助于减轻插座中的重量和热量积聚。因此，建议进一步分析它们在经股骨窝准备中的应用，以降低截肢者的代谢成本。6wt%的MWCNT。与未增强的聚酯夹层结构复合材料相比，0.6 wt% MWCNT 增强的夹层结构复合材料的热导率和弯曲强度分别提高了 68.4% 和 11.4%，对于 2-10 层袜子。0.6 wt% MWCNT 增强的夹层结构复合材料可能有助于减轻插座中的重量和热量积聚。因此，建议进一步分析它们在经股骨窝准备中的应用，以降低截肢者的代谢成本。6wt%的MWCNT。与未增强的聚酯夹层结构复合材料相比，0.6 wt% MWCNT 增强的夹层结构复合材料的热导率和弯曲强度分别提高了 68.4% 和 11.4%，对于 2-10 层袜子。0.6 wt% MWCNT 增强的夹层结构复合材料可能有助于减轻插座中的重量和热量积聚。因此，建议进一步分析它们在经股骨窝准备中的应用，以降低截肢者的代谢成本。6 wt% MWCNT 增强的夹层结构复合材料可能有助于减轻插座中的重量和热量积聚。因此，建议进一步分析它们在经股骨窝准备中的应用，以降低截肢者的代谢成本。6 wt% MWCNT 增强的夹层结构复合材料可能有助于减轻插座中的重量和热量积聚。因此，建议进一步分析它们在经股骨窝准备中的应用，以降低截肢者的代谢成本。
