Material characterizationof CBPBHA composites.(A)DSC thermograms of various CBPBs. (B) In vitro degradation of CBPBHA-90, CBPBHA-100, and CBPBHA-0 composites (PBS; 37 °C) at 1, 2, 4, 8, 12 and 24 weeks of incubation. (C) Compressive modulus of CBPBHA composites. (D) Compressive peak strength of CBPBHA composites. X-axis values represent the total CUPE percentage in CBPBs. All CBPBHA composites were polymerized at 80 °C for 5 days and 120 °C under 2 Pa vacuum for 1 day. Data are expressed as the mean ± S.D. (n = 6) and (* represents significance at p < 0.05).
