Research on the microstructure and mechanical properties of PEEK composite 3D printed prefabricated wire
In order to optimize the comprehensive mechanical properties of polyetheretherketone(PEEK)materials,researchers prepared composite PEEK filaments containing different proportions of carbon fiber(CF)and glass fiber(GF).Researchers used the GB/T 1447-2005 fiber-reinforced plastic tensile performance test method to test the mechanical properties of composite filaments containing different components,and studied their microstructure using scanning electron microscopy(SEM).The results indicate that the strength of PEEK/CF composite wire increases with the increase of CF content.The strength of PEEK/GF composite wire also increases with the increase of GF content.The strength of composite wire with 10%GF added is significantly higher than that of pure PEEK wire,but the overall strength improvement is slow as the GF content continues to increase.
