Abstract
Providing composite structures with micro contoured surface layer. There is provided a method to adjust roughness level of micro contoured surface layer when manufacturing a composite and products thereof. The micro contoured surface layer may cover all or at least part of the surface area of the composite product. The roughness level of micro contoured surface layer may be increased or decreased by controlling the process parameters. In particular, there is provided a method to increase the roughness level of composite material having a primary surface layer with a primary surface roughness by softening the primary surface layer of the composite material by heating and providing a secondary surface layer of the composite material surface with a secondary surface roughness by cooling the softened surface layer. Further, there are provided methods to determine and visualize the level of micro contoured surface layer roughness on a composite product surface.
