Abstract:Objective The purpose of this study is to evaluate biomechanical character of continuous carbon-fiber reinforced polyolefin composites as hard tissue repair material. Methods Twenty-five rods of continuous carbon-fiber reinforced polyolefin were subjected to the tests of anti-bending, compressive strength, shear strength and flexural strength. The result included elastic modulus, tensile strength, Compressive strength, anti-bending strength, shear strength and poisson' s ratio. Results Elastic modulus: (43.33±1.17) GPa,tensile strength: (561.11±14.24) MPa,shear strength: (58.20±15.28) MPa,flexural strength: (715.86±19.26) MPa,Poisson' s ratio: 314±0.005, Elongation: (18.20±0.55) %, Compressive strength: (0.341.91±1.71) MPa. Conclusion This work revealed that the continuous carbon-fiber reinforced polyolefin composites have more ideal biomechanical Properties. It meet the biomechanical demends of hard tissue repair.
