Question

Consider the following statements:Carbon fibres are used in the manufacture of components used in automobiles and aircrafts.Carbon fibres once used cannot be recycled.Which of the statements given above is/are correct?

Accepted Answer

Carbon fibers can be defined as fibers with a carbon content of 90% or above. It is made up of long, thin strands of carbon that are bonded together. Carbon fiber is made by heating a carbon-containing material, such as polyacrylonitrile (PAN), rayon, or pitch, to a very high temperature in an inert atmosphere. This process causes the carbon atoms to bond together and form long, thin strands. The strands are then twisted together to form yarn, which can be woven into fabric or mats. The fabric or mats can then be impregnated with a resin, such as epoxy, to form a composite material.It is very strong and lightweight, and they are also corrosion-resistant and have a good electrical conductivity. Thus making it ideal for use in a variety of applications, including aircraft manufacturing and automobiles. Hence statement 1 is correct.Carbon fibre is not currently biodegradable. Because carbon fibre is a composite built to hold its strength and shape – most carbon fibres are difficult to recycle and repurpose – especially since they cannot be melted down and used to make new products or items. Currently, carbon fibre waste or other fibre composites can be recycled using several types of technologies including:virgin carbon fibre offcutscarbon fibre-reinforced composites (CFRC)utilizing chemical reactionssize-reduction method using high-voltageelectrohydraulic and electrodynamic fragmentationHence statement 2 is incorrect.
