Q83.
Consider the following statements: 1. Carbon fibres are used in the manufacture of components used in automobiles and aircrafts. 2. Carbon fibres once used cannot be recycled. Which of the statements given above is/are correct?
Answer
A
Explanation
fibers can be defined as fibers with a carbon of 90% or above. It is made up of long, thin of carbon that are bonded together. fiber is made by heating a carbon-containing such as polyacrylonitrile (PAN), rayon, or to a very high temperature in an inert process causes the carbon atoms to bond together form long, thin strands. The strands are then together to form yarn, which can be woven into or mats. The fabric or mats can then be with a resin, such as epoxy, to form a material. is very strong and lightweight, and they are also and have a good electrical Thus making it ideal for use in a variety of including aircraft manufacturing and Hence statement 1 is correct. fibre is not currently biodegradable. Because fibre is a composite built to hold its strength and – most carbon fibres are difficult to recycle and – especially since they cannot be melted and used to make new products or items. carbon fibre waste or other fibre composites be recycled using several types of technologies virgin carbon fibre offcuts, carbon fibre- composites (CFRC), utilizing chemical size-reduction method using high-voltage, and electrodynamic fragmentation. statement 2 is incorrect.
