Composite materials are made of two or more macro constituents with different shapes and compositions.

Composite materials are used in aerospace, underwater, transport, automotive, home appliances, and sporting goods industries.

Composite materials are made from metals, ceramics, and polymers.

The matrix is the continuous material surrounding the dispersed phase within a composite.

Composite material properties depend on the materials used, their proportions, and the structure of the dispersed phase.

In fiberglass, the polymer matrix holds the glass fibers, protects them, and distributes forces.

Wood is a natural composite.

Composites are chosen for their overall optimal combination of properties, not just one specific property.

Composite properties depend on the component materials, their shapes, and interactions.

Large particle composites use a stronger, stiffer dispersed particle, while dispersion-strengthening uses smaller particles to impede movement of dislocations.

The distributed phase in particle-reinforced composites is equiaxed (same dimensions in all directions).

Composites are categorized as particle-reinforced, fiber-reinforced, and structural composites based on the matrix and reinforcement.
