Carbon fibres — used in automobiles/aircraft; cannot be recycled once used
Question
Consider the following statements: Which of the statements given above is/are correct?
- 1.
Carbon fibres are used in the manufacture of components used in automobiles and aircrafts.
- 2.
Carbon fibres once used cannot be recycled.
Options
1 only
2 only
Both 1 and 2
Neither 1 nor 2
Explanation
Statement 1 is correct; carbon fibers are highly valued in aerospace and automotive industries for their exceptional strength-to-weight ratio.
