Application advantages of carbon fiber composite materials in the medical field
01 Anisotropy and Designability
Carbon fiber composite materials are anisotropic materials. They have different properties along the fiber direction and perpendicular to the fiber direction, which brings a great degree of freedom to the design. The properties of the product can be changed by changing the plying method (such as plying angle, plying sequence). Characteristics such as elasticity and strength to meet specific usage requirements. Medical equipment components often act on different parts of the human body, and different components have different specific performance requirements.
02 High X-ray transmittance
The transmittance of X-rays is related to the elemental composition, atomic number, density, and thickness of the penetrated material. The main elements that make up carbon fiber composite materials are C, H, and O. The atomic numbers are small, and the X-ray mass absorption coefficient is much lower than - general materials. The X-ray transmittance of 1mm thick aluminum plate and carbon fiber composite plate is 78% and 96% respectively. The scattering and absorption consumption of the aluminum plate is 22%, and the carbon fiber plate is only 4%.
03 Good fatigue resistance
Carbon fiber composite materials contain numerous fiber/resin interfaces. When cracks occur when subjected to excessive external force, these interfaces can effectively prevent further expansion of cracks and delay the occurrence of fatigue damage. Medical devices are reused every day, and the good fatigue resistance of carbon fiber composite materials ensures the service life of the instruments.
In the field of medical devices, carbon fiber composite materials are used to manufacture mobile platforms for X-ray inspection instruments by taking advantage of their full X-ray transmittance. Using CFRP's excellent mechanical properties, they are used to manufacture medical devices such as orthopedics and organ transplantation. and manufacturing prosthetics, orthotics and other rehabilitation products.
