aggregates and composite materials

What is the difference between composite and

is that composite is a mixture of different components while aggregate is a mass, assemblage, or sum of particulars; something consisting of elements but considered as a whole. As verbs the difference between composite and aggregate is that composite is to make a composite while aggregate is to bring together; to collect into a mass or sum.
