1. Correct. Carbon fibres are widely used in automobile and aircraft components because they are light, strong, and corrosion-resistant.

2. Incorrect. Carbon fibres/composites can be recycled through processes such as mechanical, thermal, or chemical recycling; hence it is wrong to say they cannot be recycled once used.
