Composites for hard tissue repair.
COMPOSITES FOR HARD TISSUE REPAIR
deposit new bone, osteocytes that are present throughout
mature bone, and osteoclasts that resorb old and damaged
bone. The properties of bone as a composite material are
discussed in greater detail in the article titled Composite
Scaffolds for Bone Tissue Regeneration elsewhere in
this handbook. Hard tissue implants could either be going
into or on to the shaft of bones and, thus, can contact
cortical or cancellous bone or both. Young’s modulus of
cortical bone is 7–25 GPa, while that for cancellous bone
is 100–1000 MPa and their strengths are 50–150 and
