Composites

Question 1

What are 3 types of properties a material can have?

-Oscar Lawson

Answer 1

Mechanical
Chemical
Physical

Question 2

What are examples of a Particle Composite material?

-Oscar Lawson

Answer 2

MDF (Wood+resin)
Concrete (Cement+sand+stone)
Sintered Metals

Question 3

How do you sinter metal?

-Oscar Lawson

Answer 3

Heat it and/or add pressure to shavings of metal that would otherwise be wasted. This should compact them into one material but shouldn’t melt them.

Question 4

What are examples of Laminate composites?

-Oscar Lawson

Answer 4

Plywood 
Laminated glass (Safety glass+polyvinyl butyral)

Question 5

What are examples of Fibrous/Stranded composites?

-Oscar Lawson

Answer 5

GRP (Glass reinforced polyester/fibreglass- glass fibres+polyester resin)
Reinforced concrete (Concrete with steel rods for tensile strength)
