Investigation of Compression and Hardness for UHMWPE Bio-composites as Internal Bone Plate Fixation

Bone plates are essential for bone fracture healing because they modify the biomechanical microenvironment at site to provide necessary mechanical fixation fragments. This paper addresses use of composite in long-bone fractures such as transverse femur. However, stress shielding due metal can be reduced by designing implants with Bio-composites that involve Ultra high molecular polyethylene reinforced (UHMWPE) Nano hydroxyapatite (n-HA) and titanium dioxide (n-TiO2) particles different weight fraction (0,1.5,2.5,3.5and 4. 5%) 5% carbon Kevlar fibers. FRIT spectrum was used identify incorporation between matrix particles, shifting main peaks confirmed good cross-linking within structure. The specimens thus prepared were subjected a compression test, hardness density. results indicated UHMWPE+4.5%n-HA+CF hybrid biocomposite has highest compressive strength properties. In contrast, UHMWPE+4.5%TiO2+CF density, which increased increasing percentages Nano-particles, where 53 MPa, property ranges 65.6 shore D, density 1.09 (g/cm3). According current study's findings, it is possible create bio-composites internal device improved performance placing fiber reinforcements.
