answer wiki. here are some examples of the most commonly used composite materials: concrete is the most common artificial composite material of all and typically consists of loose stones (aggregate) held with a matrix of cement. concrete is an inexpensive material and will not compress or shatter even under quite a large compressive force.

history of composites - composites 101 | compositeslab

one of the earliest uses of composite material was by the ancient mesopotamians around 3400 b.c. when they glued wood strips at different angles to create plywood. the concept of “composite” building construction has existed since ancient times.
