IMPORTANCE OF CARBON FIBRE IN ORTHOPEDIC PROSTHETICS
The implementation of Carbon fibre in the field oforthopedic prosthetics is for the purpose of providing the definitive socket that the patient receives after the test socket has been approved by the doctors. The design of the socket is basically determined by the kind of prosthesis that the patient is receiving and customizes the outer design of the socket according to their liking.
One of the greatest leaps in technology occurred during the last (5 to 10) years due to the increase in usage of light-metal alloys and carbon fibre composites for the production of prostheses. Modern prosthetic devices help a lot of individuals across the world to partially compensate for their missing limbs & lead a life of high quality.
MODERN MOLDING TACTICS:
One of the most significant features of modern prosthetics is the fact that they can be custom-made to match the weight, height, & muscular structure of an individual. It’s almost impossible to give the prosthesis the desired shape with the help of manufacturing processes that involve machining. Thus, the material that is to be used has to be the perfect fit for the molding manufacturing technologies. One of the greatest advantages of fibre composites is that they lend themselves to the production of deep components with compound curves and thin walls.
VARIATION OF MECHANICAL PROPERTIES
A prosthesis can replicate all the functions of the natural organ that it replaces. Thousands of years of evolution have converted the human bones & muscles into perfect structures with a high resistance/weight ratio & varying properties across the different regions. With the advent of recent technologies in the molding processes of composite materials, it’s possible to obtain various levels of strength in the different regions of a particular component.
LEVEL OF SPECIFIC STRENGTH:
Among warm-blooded animals, tendons and muscles facilitate the different movements of the body, while bones & joints are regarded as the weight-bearing components. Prosthetics that are presently approved by the existing medical authorities are regularly used in practice for the proper functioning of bones.
Currently, available epoxy composites have the potential to easily produce a tensile strength of around 700 MPa & a modulus elasticity of 70 GPa. Along with its density of 1.6 g/mL, the higher specific strength of this material becomes more evident.
One of the most notable characteristics of proteins that are found in the muscles & tendons are called elastin and myelin, and it acts as a spring in a steady state. Over a duration of many years, elastin, which is known as the main building block of tendons, has successfully evolved into a perfect “Hookean Solid”. Some of the perfect examples of such materials include a rubber band or steel spring.
During the selection of a material for the production of carbon fibre, epoxy composites stand out as the primary material of choice because of a number of factors, including their compressive strength, modulus, tensile strength, fatigue resistance, impact resistance, ease of manufacturing, hygiene, specific weight, and aesthetic factors. Tens and thousands of people worldwide are living a better & more fulfilling life due to the carbon composite prosthetics.
