Bone plates are internal fixation devices used for fractured bone healing. Conventional bone plates made of metals can occasionally cause a range of problems, such as stress shielding, corrosion and loosening as well as a need for additional surgery to remove the plates. To resolve these problems, polymer based composite materials with desirable mechanical properties, biodegradability, and biocompatibility have been suggested for bone plate fixation as an alternative of the metal materials. In this study, a silk fibroin/cellulose composite bone plate was prepared in an aqueous system. The tensile modulus and strength of the composite bone plate were examined using a universal testing machine, and the flexural yield strength of the composite bone plate was measured using a four-point bending test. Field emission scanning electron microscopy was used to examine the morphology of the composite bone plate. |
