摘要：

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. (C) 1999 Elsevier Science Ltd and Techna S.r.l. All rights reserved.
