    Key Questions:

    1. What is the chemistry name for plastics?
      • Plastics are polymers.
    2. What determines how a polymer is used?
      • The properties of the polymer determine how they are used.
    3. Name four properties of some polymers.
      • Polymers can be flexible, cheap, electrical insulator, strong, tough resistant to chemicals and generally have a low density.
    4. What is a composite material?
      • Composites are made up of more than type of material.
    5. Why are composites used?
      • Composites have a mixture of properties from the materials that make them up.
    6. Explain why reinforced concrete used for bridges?

    7. What are glass Reinforced Plastics?
      • Glass ReinForced Plastics (GRP) are a composite of glass fibres (ceramic) and a plastic (polymer).
