Abstract

Femur fractures are often treated by fixing metallic bone plates in the fractured area. But metallic bone plates are subjected to stress shielding. To overcome stress shielding, a material with similar strength and stiffness to that of the human bone can be better suited. The present study focuses on the fabrication of carbon-flax/bioepoxy hybrid composite. The femur bone plate was modeled using SOLIDWORKS®2020 3D modeling software package. Hybrid composite laminates were developed using compression molding technique and material characterization studies viz. Tensile, shear, flexural and wear tests were conducted on the ASTM shaped specimens to estimate the strength and wear properties of the fabricated hybrid composite. The results of the tests indicate that the Carbon-flax reinforced hybrid composite have properties similar to that of human femur bone and seems to be a better option for the replacement of metallic bone plates.
碳-亚麻增强生物环氧复合材料骨板的力学和摩擦学性能研究
股骨骨折通常通过在骨折区固定金属接骨板来治疗。但金属骨板受到应力屏蔽。为了克服应力屏蔽,一种强度和刚度与人类骨骼相似的材料可能更合适。研究了碳-亚麻/生物环氧杂化复合材料的制备。采用SOLIDWORKS®2020 3D建模软件包对股骨骨板进行建模。混合复合材料层压板采用压缩成型技术和材料特性研究,即拉伸、剪切、弯曲和磨损试验进行了ASTM成形试样,以估计制造的混合复合材料的强度和磨损性能。试验结果表明,碳-亚麻增强复合材料具有与人类大腿骨相似的性能,似乎是替代金属骨板的较好选择。
