Glass fiber reinforced concrete composites contain high strength glass fibers that are surrounded by a cementitious medium. In this shape, both the fibers and the environment maintain their natural individual chemical characteristics. However, the concrete produced has improved resultant properties that cannot be attained if either of the components is used individually. The glass fibers are the main elements that carry the load, while the enclosed matrix keeps the fibers in the preferred position and direction. The medium facilitates transfer of the load on the fibers, and shields them from the damage due to environment. Glass fibers can be integrated into the matrix either in constant or irregular lengths. The most widespread shape in which glass fiber reinforced composites are used in structural applications is known as laminate. This form is achieved by consolidating fine fiber layers and a matrix into the desired size. The orientation of fiber in each layer, and the stacking sequence of the layers, can be used to produce a range of mechanical properties of the composite materials.
