Why is combining used in materials
Numerous metals make a lightweight strong material
Why is compositing materials used
Provides strength and reinforces materials
3 examples of composite materials
Polymer Matrix Composites (PMCs)

What is a smart material (2)
Materials that respond to external stimuli (e.g. Stress, temperature, electricity)
Change their properties
What are modern materials (2)
Made using new/modern processes
Improve on existing materials
Example of a shape memory alloy
Nitinol (Nickel and Titanium)
Piezoelectric materials (2)
React to an electrical charge
E.g. Stamp to light up shoes
Thermochromic pigments (3)
Change colour in response to changes in heat
Cookware, kettles, baby food containers
Prevents accidents and injury
