Ceramics, Polymers & Composites

Science · Matter & Materials · conceptual

Describe the properties and uses of ceramics (hard, brittle, heat-resistant), polymers (flexible, lightweight, variable), and composites (combine properties of constituent materials), giving real-world examples of each

What mastery looks like

  • Gives the key properties of ceramics, polymers, and composites with examples of each
  • Explains why a composite material is used rather than a single material in a given application (e.g. carbon-fibre reinforced plastic in bikes)
  • Identifies natural and synthetic polymers
  • Explains why polymer properties can be tailored during manufacturing

Check your understanding

If Ceramics, Polymers & Composites was looking at a racing bicycle made of carbon fibre, could they explain why neither carbon nor plastic alone would work as well — and what makes the combination a composite better than either material on its own?
