Abstract: A kind of degradable and absorbable composite for bone fracture fixation with high strength and module is presented, which is made of unidirection CPP/PLLA fiber composite. The property test shows that its mechanics property goes high with the addition of volume fraction(Vf)of fiber. The test results are as follows：when Vf =0.42, its bending strength is 347 Mpa, its bending module is 22 Gpa, its tensile strength is 278 Mpa, its compress strength is 178 Mpa, and its shear strength is 85 Mpa. All of them are higher than the property of human body’s compact bone.After degrading for 15 weeks in artificial degra-dation solusion at 37℃ in vitro, its bending strength becomes 154 Mpa and its bending module becomes 6 Gpa. So it can used as materials of bone fracture fixation for cancellus or partical cortical bone.
