The results show that the amorphous PLGA fiber with porous structure (0.1-1.0 μm) is obtained by diluted solvent spinning method and the mechanical properties is affected by pressure and temperature. Bending strength and shearing strength of the samples increase firstly and then decrease with the increase of molding temperature and pressure. While the molding temperature is 160℃and the pressure is 105MPa, the PLGA materials possess optimal mechanical properties, bending strength, shearing strength and bending modulus 187.3 MPa, 100.0 MPa and 2.5 GPa, respectively. The mild temperature molding PLGA materials are desired to play a grate role in non-bearing internal fixation devices.
