Q. Consider the following statements regarding Carbon Fibre:

1. It is a much lighter material compared to steel and aluminium.
2. It can be easily melted down and recycled.

Which of the above statements is/are correct?
Answer: Only 1
Notes: Statement 1 is correct as carbon fibre is significantly lighter than steel and aluminium, while offering high strength. Statement 2 is incorrect because carbon fibre composites are not easily melted down and recycled; the polymer matrix cannot simply be remelted. Recycling usually involves burning off or chemically dissolving matrix materials to recover the fibres.
