Fig. 12. Compressive mechanical properties of PCL-CaP composites scaffolds. A:
Comparison of the compressive modulus of 100% PCL, 90:10 and 80:20 PCL-CaP scaffolds;
B: Comparison of the ultimate compressive strength with different concentrations of CaP.Figure 12 summarized our compressive testing results for scaffolds with 600μm pores. We
noticed the same trend as the cylinders: with the increasing CaP contents, the mechanical
performance of scaffolds improved. The 600μm pure PCL scaffolds had UCS values of
2.7770.26MPa and a CM of 43.973.15MPa while the 90/10 PCL-CaP scaffolds had UCS
value of 3.210.53MPa, CM of 46.66.49MPa and 80/20 had UCS of 3.7020.207MPa, CM of
