ABSTRACT

In an advanced society like ours, we all depend on composite materials in some aspects of our lives. Composite materials have a long history of usage. Their beginnings are unknown, but all recorded history contains references to some form of composite

material. For example, straw was used by Israelites to strengthen mud bricks. Plywood was used by ancient Egyptians when they realized that wood could be rearranged to achieve superior strength and resistant to thermal expansion as well as to swelling owing to the presence of moisture. Medieval swords and armor were constructed with layers of different materials.
