A two-step method was used to prepare poly L-lactide(PLLA)/ β-calcium metaphosphate (β-CMP) fracture fixation composites. The mechanical strength of these composites is tested and the factors which will affect the mechanical strength were analyzed. The experimental results showed that the bending strength and Young’s modulus of composites prepared by the two-step method were much better than those prepared by the two-step method, reached a maximum of 126.33 MPa and 4.36 GPa, which are close to those of the cortical bone and can meet the request of internal fixation for human bone fractures.
