• Strengthener

One benefit of using a composite material in manufacturing is that they

• Look smart.

• Have good electrical conductivity.

• Are cheap.

• Can easily be produced into complex shapes.

A composite material is made of 

• A single material
• Two or more separate materials
• Two or more chemically combined materials
• None of these

A composite material has:

• The same functionality as its components
• Lower functionality than its components
• Higher functionality than its components
• None of these

What is the matrix of a composite?

• The strengtheners of the composite
• The base of the composite
• The mold that the composite is poured in 
• The volume of a composite

What are the reinforcements of a composite?

• The strengtheners of the composite
• The base of the composite
• The mold that the composite is poured in 
• The volume of a composite
