ABSTRACT
This chapter highlights various applications of carbon fibers (CFs)-reinforced composite materials. Plasma treatment is a cleaner method to activate the surface of CFs. Oxygen, argon, ammonia, and so on treated with plasma ions are used to activate the surface of CFs. The effect of metal coating on CFs produces far better results than metal oxide and bare CFs. The coating enables the interface of CFs and matrix material to create a strong bond. CFs have high crystallinity and strong covalent bonds with a graphitic structure. CFs have highly anisotropic mechanical properties. CFs possess high strength and have a density comparable with that of bone. These materials have been developed with epoxy-based composite materials. Earlier the titanium-based implants have been used for the same purpose. Drug delivery is a very attractive method in medicine that refers to the transfer of a medicinal compound in the existing body to induce a desired therapeutic effect with the least side effects.
