Q

what are examples of man made composites

A

concrete, steel-reinforced concrete, plywood and safety glass

17
Q

what are some examples of natural composites

A

wood and bone

18
Q

what are composites made of

A

one material is the reinforcement and the other is the matrix

19
Q

what does the matrix do

A

it surrounds and binds together fibres or fragments of the reinforcement

20
Q

why is a composite material stronger, harder tougher and more lightweight than a single material

A

it has useful properties from both the materials used to make it

21
Q

what is glass reinforced plastic used to make

A

boat hulls and car bodies

22
Q

what is safety glass used to make

A

car windscreens as they are hard and rigid and don’t break into small pieces when impacted

23
Q

what is steel reinforced concrete used to make

A

construction of buildings as it is strong in tension and compression

24
Q

what is kevlar used to make

A

bulletproof vests

25
Q
