Ceramics, Polymers & Composites
陶瓷、聚合物与复合材料
Description
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
Mastery Evidence
- 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
Assessment Prompt
If your child 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?
