1, excellent mechanical properties
Carbon fiber composites have the characteristics of high strength and light weight, with high specific strength and specific modulus; in the medical equipment, it can be used for the parts that need good rigidity and light weight requirements.
2, anisotropy and designability
Medical equipment, some parts, need to be loaded in a certain direction after the deflection is very small, has a high degree of rigidity; carbon fiber reinforced resin matrix composites can have significant anisotropy, that is, along the fiber axial and perpendicular to the fiber axis has a significant difference in the performance of the material anisotropy to the design of a greater degree of freedom.
3, excellent X-ray transmission performance
X-ray penetration of the material after the intensity of attenuation or the degree of absorption is related to the composition of the material, atomic number, density and thickness. For carbon fiber composites, the resin's elemental composition of C, H, O, carbon fiber's elemental composition of C, X-ray mass absorption coefficient are very small, much lower than the general material. Carbon fiber composites of aluminum equivalent of 0.11, carbon fiber composites foam sandwich structure of aluminum equivalent of 0.52, X-ray transmission performance are greatly superior to aluminum, plywood and phenolic resin panels and other traditional medical materials. And carbon fiber composites allow rays to be irradiated at any angle on the bed plate without refraction.
4, good fatigue characteristics
Because of the large number of patients, the fatigue performance requirements for bed panels are high. In carbon fiber reinforced resin matrix composites, there are uncountable fiber / resin interface, these interfaces can prevent cracks from further expansion, thus delaying the occurrence of fatigue damage. During use, even if a small number of fibers are fractured due to overloading of the composite member, the load will be quickly redistributed to the undamaged fibers so that the entire member will not lose its load-bearing capacity within a short period of time, demonstrating that the structure has a good breakage safety.
