Question 5

What is a composite

Answer 5

A composite material consists of two of more materials with different properties. They are combined to produce a material with improved properties. Most composites have a reinforcement and a matrix (something that binds the reinforcements together). For example, Reinforced concrete using steel and concrete to improve the compressive and tensile strength.

Question 6

What is a polymer

Answer 6

A polymer is a long chain molecule made up of repeating units. A polymer can be made synthetically by combining many small molecules called monomers

Question 7

What is an Alloy

Answer 7

An alloy is a mixture of two or more elements where at least one element is a metal. Many alloys are mixtures of 2 or more metals.
