    • 1 only<\/li>\n\n\n\n
    • 2 only<\/li>\n\n\n\n
    • Both 1 and 2<\/li>\n\n\n\n
    • Neither 1 nor 2<\/li>\n<\/ul>\n\n\n\n

      • Carbon fibers can be defined as fibers with a carbon content of 90% or above<\/strong>. They are produced by thermal conversion of organic fibers with a lower carbon content such as polyacrylonitrile (PAN)<\/strong> containing several thousand filaments with diameter between 5 and 10 \u03bcm.<\/li>\n\n\n\n
      • The main advantage of carbon fibers compared to other fibers are the high tensile strength, high stiffness, low density, and a high chemical resistance.<\/strong><\/li>\n\n\n\n
      • Carbon fibre is increasingly celebrated as a wonder material<\/strong> for the clean economy. Its unique combination of high strength and low weight<\/strong> has helped drive the wind power revolution and make planes more fuel efficient.<\/strong> Auto makers<\/strong> are also waking up to the material\u2019s potential to make lighter and more efficient vehicles.<\/strong><\/li>\n\n\n\n
      • The carbon fibre can be recycled though <\/strong>difficult to recycle.  <\/strong>There is need to divert carbon fibre from landfill, they could open the gates for use of recycled carbon fibre in cars, bikes and for dozens of other applications.<\/strong> They could also save a lot of energy, since the production of virgin material is the most energy-intensive part of the process. Recycled carbon fibre often ends up in tennis rackets and golf clubs,<\/strong> where low weight (and the cachet of carbon fibre) is more important than strength.<\/li>\n<\/ul>\n\n\n\n
