Composites and the Application of Non-Destructive Testing
As the name suggests composite materials are heterogenous, resulting from combinations of two or more distinct materials. In composite materials the combination of materials is at the macroscopic level, resulting in discrete interfaces separating the constituent elements. When we think of composite materials, polymer-based variants are usually the first to come to mind such as carbon fibre reinforced polymers or glass fibre composites. However, there are also naturally occurring composite materials such as wood. Another commonly used but often overlooked composite material is concrete. Composites need not be complicated, something as simple as papier-mâché, a common craft material, is also classed as a composite material.
