Résumé : |
Bone plates are essential for bone fracture healing because they modify the biomechanical microenvironment at the fracture site to provide the necessary mechanical fixation for fracture fragments. This paper focuses on reducing the stress shielding effect that occurs due to a mismatch between cortical bone and metal plate. fabricating bio composites plates fixation by modeling of femur bone with ANSYS software program. However, Bio-composites that involve Ultra-high molecular weight polyethylene polymer (UHMW-PE) reinforced with nano Titanium dioxide particles n-TiO2 at different fractions (0, 1.5, 2.5, 3.5 and 4.5%) and 5% from carbon and Kevlar fibers were fabricated by hot pressing technique. We tested tensile, elastic modulus, and elongation percentages. The results of this study showed a value of tensile strength and elastic modulus improved with increasing weight fraction of nanoparticles and UHMWPE+4.5% n-TiO2 biocomposite were the best mechanical properties, were tensile strength and elastic modulus was (38.57 ± 1.9285 MPa, 1.15 ± 0.0575 GPa) respectively and elongation percentages reduced to 114.05 ±5.7025% compared with pure UHMWPE 176.68 ± 5.7025%. According to the current study's findings, it is possible to create bio-composites as fixation devices with improved performance by placing different fiber reinforcements. |
