Biomechanical evaluation of glass fiber/polypropylene composite bone fracture fixation plates: Experimental and numerical analysis

Little is known about the impact behavior of composite fixation plate used in fracture healing long bones diaphysis. Hence, this study examined polypropylene plates using different glass fibers and measured their biomechanical responses under axial loading experimentally numerically. Short randomly oriented, unidirectional prepregs fiber yarn were considered as reinforcements, fabricated through two heat-compressing 3D printing processes. Furthermore, assessing structures was carried out vitro test finite element analysis (FEA). Impact damping behavior, damage mechanisms, stress strain pattern obtained various bone fractures energies. The load-time failure mechanisms demonstrated that with more plastic lower stiffness could act an initial shock absorber dampen transmission load by distributing energy over time. Therefore, considering ability shielding adequate interfragmentary movement which amplifies ossification, proposed Glass Fiber/PP (GF/PP) serve a proper alternative orthopedics.
