Consider the following statements:
- Carbon fibres are used in the manufacture of components used in automobiles and aircraftes.
- Carbon fibres once used cannot be recycled.
Which of the statements give above is/are correct?
- 1 only
- 2 only
- Both 1 and 2
- Neither 1 nor 2
Explanation
Statement 1 is correct
- Carbon fibres are super stiff and high-strength, but are extremely light in weight. Thus, carbon fibres are widely used in various industries, including aerospace, automotive, sporting goods, construction, and manufacturing.
Statement 2 is incorrect
- Carbon fibre waste or other fibre composites can be recycled using four types of technologies Pyrolysis, Solvolysis, Depolymerization, and Mechanical Recycling.
- Recycling carbon fibre is challenging because the material cannot be easily melted down; the polymer resin must be burned off or chemically dissolved, resulting in shorter, less robust fibres.
