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?
- A1 onlyCorrect
- B2 only
- CBoth 1 and 2
- DNeither 1 nor 2
Explanation
Statement 1 is correct. Carbon fibres are widely used in the manufacture of components for automobiles and aircraft due to their high strength-to-weight ratio, stiffness, and corrosion resistance. They are used in body panels, structural components, and interior parts.
Statement 2 is incorrect. Carbon fibres can be recycled through methods such as pyrolysis (thermal decomposition) and solvolysis (chemical dissolution), which recover the fibres for reuse. While recycling carbon fibre composites is more challenging than some materials, it is not impossible.
Therefore, only Statement 1 is correct.
