抄録

Bioactive ceramics/PLLA composites have been expected to apply for the fracture fixations which have more biocompatibility than PLLA. In this study, β-TCP/PLLA composites containing three different β-TCP contents (4.8, 9.5, 14.3wt%) were prepared by injection molding. The results of bending tests show bending strength decrease with increasing β-TCP contents. On the other hand, bending modulus increase with β-TCP contents. After immersion tests in PBS at 37℃ up to 8 weeks the mechanical properties in all specimens did not change significantly. Predictions of stress-strain curve based on damage mechanics were in good agreement with experimental results.
