Carcinogenicity of metal alloys in orthopaedic prostheses
Carbon fibre reinforced plastic applied to prosthetics …
In the same price range as many exoskeleton products, INDEGO costs roughly US$80,000. Gormley says personal lifelong use is a definite goal, but the cost is a factor and work is still needed to document its health benefits and usage outcomes if users are to obtain health insurance reimbursements. Parker Hannifin has started a four-year, multi-center study funded by the US Department of Defense and the Congressionally Directed Medical Research Programs to do just that. Ekso Bionics also has received FDA approval for its Ekso GT product to be used with stroke and spinal cord injury (SCI) patients, while the US Department of Veterans Affairs (VA, Washington, DC, US) has issued a national coverage policy for ReWalk Robotics Inc.’s (Marlborough, MA, US) robotic wearable exoskeletons for qualifying veterans with SCI. Veterans will be evaluated for use of the device, which uses CFRP footplates to support the patient’s weight, while powered hip and knee motion enables the patient to stand upright and walk independently. Training will begin on an outpatient basis and proceed to home or community settings, followed by consideration for procurement of a personal device for long-term use. Although both ReWalk and Parker Hannifin are focused primarily on rehabilitation products, Parker also is pursuing human augmentation products via its investment in and partnership with Freedom Innovations (Irvine, CA, US), which uses CFRP in a number of its standard prosthetic devices and component upgrades.

Carbon fibre prostheses and running in amputees: A …
The layers in the fibers are formed by strong covalent bonds. The sheet-like aggregations readily allow the propagation of cracks. When the fibers bend they fails at very low strain. In other words carbon fibre does not bend much before failing.
I want to know whether jute fibre can be used for making carbon fibre
Test have shown that failure is unlikely to be a problem when cyclic stresses coincide with the fiber orientation. Carbon fiber is superior to E glass in fatigue and static strength as well as stiffness.

Composites made from carbon fibre must either be made with UV resistant epoxy (uncommon), or covered with a UV resistant finish such as varnishes.
