The effect of using nano particle size of Hydroxyabatite to produce HA/HDPE biocomposite
by Hot Pressing technique was studied by investigating the effect of particle
size and production technique on the physical and mechanical properties of the biocomposite
at different volume fraction of nano HA powder and different compression
Nano particle size and Hot Compression technique had great impact on the properties
by reversing the behavior of the bio composite comparing with that using micro scale
particle size in some of previous studies .The fracture strength and hardness increased
with increasing the filler content by more than 200% for strength and 300-400% for
micro hardness values , the densities increased with increasing filler content
compressing pressure where as the porosity decreased.
The modification in mechanical properties due to filler particle size and production
process enhanced the osteo- conductivity of biomaterial to use in different bone substitute
