Preparation and properties of dense and porous calcium phosphate

A dense tricalcium phosphate possesses E- and shear-modulus of 115 and 86 GPa, respectively. By polyurethane foam and C-fibres a high porous structure with integral porosity of 55–70% was created. The porous tricalcium phosphate possesses a E-modulus of 2–5 GPa, bending strength of 6–11 MPa and comp...

Zusammenfassung:	A dense tricalcium phosphate possesses E- and shear-modulus of 115 and 86 GPa, respectively. By polyurethane foam and C-fibres a high porous structure with integral porosity of 55–70% was created. The porous tricalcium phosphate possesses a E-modulus of 2–5 GPa, bending strength of 6–11 MPa and compressive strength of 11–22 MPa. Regarding mechanical properties this system could be ranged between cortical and cancellous bone. ©
