What is a “Composite”? Definition 2: A composite is a mixture of two or more distinct constituents or phases. 1. Both constituents have to be present in reasonable proportions (say 5% or more) 2. Constituents have different properties, and hence the properties of the composite are distinctly different form those of the individual constituents. 3. Man-made (synthetic) composite is produced by intimately mixing the constituents by various means therefore an alloy that is formed during solidification from a homogenous melt is not normally classified as a ‘composite’.

Composites have two (or more) distinct phases. The phase that is continuous and is often present in the greater percentage in the composite is termed the Matrix ”. Typically, it is desirable to improve upon the properties of this ‘bulk’ matrix by incorporating other reinforcing constituent(s) and thus a composite is created. Examples of Properties
