# Ceramics, Polymers & Composites

Describe typical properties and uses of ceramics, the varied properties of natural and synthetic polymers, and how composites combine distinct materials. Explain how manufacturing choices change polymer properties and why a composite must suit its intended use.

## Ready when they can

- 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

## Lesson: Ceramics, Polymers & Composites

You have compared materials by their properties. Ceramics are inorganic, non-metallic materials, often made by heating clay or mineral powders. Bricks, pottery and ordinary window glass are examples. They are usually hard and heat-resistant, but brittle: under enough stress they tend to crack rather than bend. Hardness alone does not identify a composite.

Polymers contain large molecules with repeating units linked into chains. Many have low density, but some are flexible and others rigid. Natural rubber, silk, cellulose in cotton and proteins in sheep's wool are natural polymers made by living things. Nylon and polythene are synthetic polymers made by chemical reactions. Rubber can also be synthetic. Spinning wool into yarn does not make its protein polymer synthetic.

*(drawing: The wool already contains natural protein polymers before its fibres are spun into yarn.)*

Manufacturers can alter chain length, links between chains and additives. A plasticiser helps chains move past one another and can make a plastic more flexible. Effects depend on the polymer and the change, so changing chain length does not always increase stretchiness.

A composite combines distinct materials that remain distinguishable within it. In carbon-fibre reinforced plastic, strong, stiff fibres reinforce a polymer resin. The resin holds fibres in position and transfers forces between them. Composites can include metals or ceramics, so they are not all non-metallic.

**Example.** Some racing bike frames use this composite for strength and stiffness with low mass. The resin can limit heat resistance, and the frame can still crack. Test the finished material for its intended conditions; combining materials does not guarantee better performance.

**Recap.** Ceramics are usually hard, heat-resistant and brittle. Polymer properties vary and can be tailored. Composites combine distinct materials whose benefits and limits matter for the job.
