/How strong carbon fiber composites are for human use
How strong carbon fiber composites are for human use 2022-12-13
Carbon fiber composite material, also known as carbon fiber reinforced plastic, has excellent mechanical properties and corrosion resistance. It has been widely used in industrial production, sports and outdoor, medical equipment and other fields. It has good compatibility with human body and can be used as artificial bone, joint, dental root canal post and other implants. Carbon fiber composites are safe and reliable in civil applications.

Carbon fiber vs. carbon fiber composite

In real life, many people tend to confuse the concept of carbon fiber and carbon fiber composite materials.

Carbon fiber is not used directly in aerospace and civil fields, but carbon fiber composite materials. Carbon fiber composites, also known as carbon fiber reinforced plastics, are composed of carbon fiber and resin matrix. So outside of the manufacturing process, people don't touch carbon fiber at all. They touch a resin matrix, which is no different from common plastic products.

Carbon fiber composites are widely used

Carbon fiber composites have been widely used in civil fields, and their popularity in foreign markets is far greater than that in China.

Industrial production

Carbon fiber composites are widely used in various corrosion resistant pipe containers, aircraft, ships and vehicle structural parts in industrial production.




Outdoor sports
Carbon fiber composites are also widely used in outdoor sports products such as badminton rackets, tennis rackets, fishing rods, bicycles and tents.


Medical apparatus and equipment

In the field of medical instruments, it is used to make mobile platform for X-ray examination instrument by its full transmission of X-ray. Using CFRP's excellent mechanical properties, it has been used in the manufacture of orthopedic and organ transplantation and other medical devices, as well as the manufacture of prosthetics, orthotics and other rehabilitation products.




Carbon fiber composites are used extensively in the human body

At present, some companies have developed artificial bones and joints made of carbon fiber composite materials. The bending strength of this artificial bone is closer to that of real human bone than that of artificial bone made of other biological materials, which is of great significance to orthopedic medicine. The wear resistance of the artificial joint made of it at the movable joint is also higher than that of ultrahigh molecular weight polyethylene and metal products.




Better biocompatibility
At present, carbon fiber composites have been widely used in bone internal fixation plate, bone filler, hip stalk, implant tooth root, skull repair materials and artificial heart materials. The bending strength of human bones is about 100Mpa, the bending modulus is 7~20Gpa, the tensile strength is about 150Mpa, and the tensile modulus is about 20Gpa. The bending strength of carbon fiber composites is about 89Mpa, the bending modulus is 27Gpa, the tensile strength is about 43Mpa and the tensile modulus is about 24Gpa, which is close to or beyond the strength of human bones.



Carbon fiber prosthesis

In addition to the advantages of modern prosthetics, which are more functional and lighter in weight, especially carbon fiber composites, they also perform well in terms of damage safety.




With excellent performance, carbon fiber composites have been widely used in civil daily life. After decades of application, they are safe and reliable to the environment and human health. With the continuous progress of medical technology, medical equipment is also constantly innovated and developed, so the application of carbon fiber in medical equipment represents a new trend and direction. How strong carbon fiber composites are for human use.
