Composite materials are created as a quite complex architecture which includes a fibre reinforcement structure and matrix material.
Introduction Composite materials are available for several decades already.
The many families of composite materials have just one thing in common: they have some kind of fibre reinforcement and some kind of matrix material to hold the fibre reinforcement in place.
