China Carbon Fiber Prosthetics Limbs In the past 5 to 10 years, the use of carbon fiber composites and light metal alloys in the production of carbon fiber prosthetic leg is the biggest technological leap. Modern prosthetic devices can help thousands of people at least partially compensate for their missing limbs and live a high-quality life. Some users engage in sports activities, even breaking records. 聽 Product Name: Carbon Fiber Prosthetic Leg Materials: Carbon Fiber and Epoxy resin *tailor made mold is required in prior Size: Customized 聽 Advantages: 聽 1/ use of modern molding technology High Gain can customize carbon fiber prosthetic leg according to individual height, weight and muscle structure. Any kind of complex structure can be produced by using split die combined with resin transfer molding and prepreg method 聽 2/ High specific strength: In warm blooded animals, muscles and tendons help the body move, while bones and joints are weight-bearing. Currently available carbon/epoxy composites easily produce a tensile strength of 700 MPa and an elastic modulus of 70 GPa. Considering its density of 1.6 g/mL, the very high specific strength of the material becomes more apparent. In addition to its tensile strength, high compressive strength and fracture toughness also help to improve the quality of this material. There are other candidates for the production of artificial limbs. 聽 3/ Ideal weight distribution: The specific strength of the carbon fiber composite is so high that a prosthesis with the same strength as the natural leg but 60% lighter can be manufactured. The carbon fiber prosthesis originally produced is indeed very light. 聽 4/ Hygiene: In addition to high strength, any material used in the prosthesis must also be easy to clean, non hygroscopic, corrosion-resistant, resistant to bacterial and fungal infections, UV resistant, insensitive to sweat and salt, and acceptable on cosmetics. After curing and washing, the epoxy resin will not stimulate human skin and will not cause allergy. Accidental skin contact with the prosthesis will not cause any harm. Carbon composites have all the required properties. 聽 5/ Elasticity: The combination of carbon fiber and epoxy resin form composite prosthetic leg which has certain degrees of elasticity that can imitate the muscle of human beings. 聽 6/ Fatigue strength: Another requirement for prosthetic materials is fatigue strength. Obviously, the load on the prosthesis does not remain constant, but changes with each step, as the device continues to bend and return to its original shape. Each known material will lose part of its strength after repeated bending for a certain number of cycles, resulting in component damage. Naturally, for prosthetic devices, it is unacceptable to gradually reduce the strength and shorten the service life. Since the 1960s, the service life of aluminum prosthesis is only one year. The cracking of polymer matrix, fiber fracture, delamination of layers and separation of matrix/fiber interface are four different failure modes observed during repeated bending. The separation at the fiber/matrix interface has the greatest impact on the component life. The curves below show the extent of strength loss due to fatigue of different materials. It can be seen from this chart that the carbon fiber/epoxy resin composite still has high residual strength after experiencing extremely high stress cycles. The use of carbon fiber/epoxy composites in wings, wind turbine blades and Formula One racing cars can prove that this material has very high fatigue strength.China Carbon Fiber Prosthetics Limbs website:http://www.hgcomposites.com/carbon-fiber-prosthetics-limbs/
