    Study Notes

    Composite Materials

    • The principle that states a better combination of properties can be achieved by combining two or more distinct materials is the concept of composite materials.
    • An example of a composite material is carbon fiber reinforced polymer (CFRP).

    Phases of Composites

    • The two main phases in usual composites are the matrix phase and the reinforcement phase.

    Categories of Composites

    • The cheapest and most widely used category of composites are polymer matrix composites.

    Properties of Composites

    • The properties of composites depend on the properties of the individual constituents, their relative proportions, and the interaction between them.
