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?
(a) 1 only
(b) 2 only
(c) Both 1 and 2
(d) Neither 1 nor 2

The correct answer is (a).

  • Carbon fibers are used in the manufacture of components used in automobiles and aircrafts. However, carbon fibers can be recycled.
  • There are four main types of technologies used to recycle carbon fiber waste: pyrolysis, solvolysis, mechanical recycling, and thermal recycling.
    • Pyrolysis is a process that uses high heat to break down the resin that binds the carbon fibers together.
    • Solvolysis is a process that uses a solvent to dissolve the resin.
    • Mechanical recycling is a process that breaks down the carbon fiber composite into small pieces that can be reused.
    • Thermal recycling is a process that uses heat to melt the resin and separate the carbon fibers.
  • Carbon fiber recycling is important because it helps to reduce the amount of waste that is produced. It also helps to conserve resources and reduce the environmental impact of manufacturing carbon fiber composites.
