  • Explain what a composite is
    a composite is a mixture of two or more materials join together to create a new enhance material.One material is known as the matrix while the other is reinforcement
  • Carbon fibre reinforced polymer
    • CFRP consists of woven carbon fibre strands encased in polymer resin
    • Carbon fibre strands have a very high tensile strength and the polymer resin is lightweight and rigid .
    • Used for tennis raquects where strength to weigth ratio is important
  • Kelvar properties
    Kelvar is:
    • lightweight
    • extreme durable
    • high tensile strength to weight ratio
    • high resistance to heat, corriosion
  • What can kelvar be used for
    it is often used in protective clothing such as police body armour where the fibre is woven in a lattice that provides protection against a knife attack
  • Glass reinforced plastic
    • GRP is a composite of glass fibres and polyester resins.
    • Glass fibres create rigidity and the resin makes GRP tough and lightweight
    • Difficult to recycle becase the process of combining glass and resin cannot be reversed
  • Use of Glass reinforced plastic
    used for
    • surfboards
    • canoes
    • car bodywork
