Contact angles are well established as a sensitive means of contamination detection on surfaces. These measurements are straightforward on flat, solid surfaces and can be extended to curved surfaces with a little effort. When the surface is either • rough, e.g., a medium grit sandpaper • a fabric of fibers • perforated with holes then it is composite in the sense that it alternates between air and substrate as one moves microscopically across the surface. It is important to understand that the contact angles reflect the composite material and not just the original solid substrate.
