Plates
for long bone fractures are a major element of internal fixation
technique includes various important developments in designs,
materials, and implementation process during the last century.
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 coir natural fiber at
different weight fractions (5, 10, 15, and 20%) were fabricated
by hand lay–up technique. Four forms of green composites; alkali
treated with 1% NaOH and untreated coir
biopolymethylmethacrylate groups A and B respectively, alkali
treated with 1% NaOH and untreated corn bioepoxy groups C and D
respectively were investigated. The mechanical properties were
tested (tensile, and compact tension) under a flow of phosphate
buffered saline PBS at 37 ◦C has been reported. The experimental
results showed that the chemical treated coir green composites
group A have the best mechanical properties than other groups
under PBS condition while the untreated coir green composites
group D have the weak mechanical properties due to plastization
by soaked in PBS solution. |
