抄録

Poly (l-lactic acid) (PLLA) and hydroxyapatite (HA)/PLLA composite plates were processed by press-process method using a hot press at a temperature close to the glass transition temperature of PLLA. Fracture energy was evaluated for the pressed and the control specimens. Fracture surface morphology was also characterized using a field emission scanning electron microscope to investigate the relationship between the microstructure and the fracture property. Single-edge-notch bending (SENB) specimens were fabricated from these pressed and unpressed plates for fracture testing. The press-processed HA/PLLA exhibited strong adhesion between the HA particle and the PLLA matrix. Interfacial strength at the HA/PLLA was effectively improved due to press processing, contributing to the improvement of the fracture energy.
