|Polycaprolactone (PCL) is a non-toxic polymer that has a very slow degradation rate and high flexibility that is suitable for use in implants but has a low compressive strength. For compensation of its poor compressive properties using bio-ceramic additives such as bioactive glasses (BG) was suggested. In this study, the effect of BG particles on the mechanical properties of PCL /BG nanocomposites is reviewed. Based on the results of mechanical tests, it was observed that by adding nanoparticles, the mechanical properties were improved. Studying the mechanical behavior of nanocomposites with different percentages of BG, demonstrate the increase in elastic modulus of nanocomposites by increment in BG loading. It has also been observed that at constant content of additive, Young's modulus of composites increases by changing the particle size from micro to submicron and nanoscale. The elastic modulus of the PCL/BG composites increased remarkably from 89±11 MPa to 383±50 MPa with increasing BG content from 0 to 30 wt.%, while still showing good ultimate tensile strength in the range of 15–19 MPa.
