Biomechanics of Natural Fiber Green Composites as Internal Bone Plate rafted

Abstract

The main purpose of this paper was to introduce a new series of green composites as a plate for bone fracture applications. These green composites offer many advantages over traditional composites and biocomposites based on synthetic polymers. In current work, the new green composites bone plate based on two types of biopolymers involves biopolymethylmethacrylate thermoplastic material and bioepoxy thermosetting material reinforced with randomly oriented corn natural fibers at different weight fractions (5, 10, 15, and 20%) were fabricated by hand lay-up technique. Four forms of green composites; treated and untreated corn biopolymethylmethacrylate groups A and B respectively, treated and untreated corn bioepoxy groups C and D respectively were investigated. The mechanical properties were tested (tensile, compression, and compact tension) under a flow of phosphate buffered saline PBS at 37 °C has been reported. The experimental results showed that the green composites group A have the best mechanical properties than other groups under PBS condition while the green composites group D have the weak mechanical properties due to plastization by immersion in PBS solution. Also, the analysis of femur bone fracture plates carried out by applying finite element method FEM using the ANSYS 16 software package.
