Select an option to attempt

Explanation

  • Carbon fibres are highly valued for their unique properties like strength, lightness, and stiffness. They are widely used in the manufacturing of various components in automobiles and aircraft to reduce weight and improve performance. 

  • Carbon Fiber Recycling: While traditional carbon fibre recycling methods were limited, advancements are being made in this field. Here are some possibilities 

  1. Mechanical recycling - This process breaks down carbon fibres into smaller pieces for use in applications where their original form is not necessary. 

  2. Chemical recycling -This method dissolves the resin holding the fibres together, potentially allowing the extraction of reusable carbon fibres. 

  3. Thermal recycling - High temperatures are used to convert the resin into usable materials while recovering the carbon fibres. 

  • These recycling technologies are still evolving, but they offer a more sustainable approach to using carbon fibres. Hence, statement 2 is incorrect.
