Slide5Metals
Typically:
Melt at high temperatures
Malleable (can be bent without snapping)
Good conductors
Made by refining and melting
ore
from the ground
Slide6Polymers
Typically:
Melt at high temperatures
Malleable (can be bent without snapping)
Good conductors
Made from joining small blocks together

Slide7Composites
Typically:
Strong
Light
Good conductors
Made by combining two materials like steel and concrete or fibres and glue.
Slide8Ceramics
Typically:
Very hard
Brittle (will smash if hit hard)
Waterproof
Made by heating material like clay in a kiln

We need the strength of steel but the lightest possible materials or vehicles.
Have you ever heard of carbon fibre? It’s a composite material. Resin is used to set strands of carbon fibres into a strong but light material.
Combining the right materials in the right way is the secret to the best products!
