Laser preparation method for strengthening and toughening ceramic bone scaffold with silicon carbide fibers
Aiming at shortcomings of low strength and toughness of a conventional bioceramic bone scaffold, the invention provides a method for preparing a novel ceramic porous bone scaffold with a biological ceramic as a matrix, SiC whisker fibers as a reinforcement body and selective laser sintering as a process; the method has the advantages that the SiC whisker fibers as the reinforcement phase are added to the bioactive ceramic, and the strength and toughness of the ceramic are greatly improved by using silicon carbide superior mechanical properties and whisker pulling-out, bridging and crack deflection effects; the bioceramic bone scaffold has the characteristics of high strength, high toughness, interconnected porosity, customizable appearance and the like, and is expected to be used in a load-bearing or dynamic load environment.
